If you have a DM who always lets you know that combat is coming up in exactly a few rounds but not many rounds and exactly what you'll be fighting, then you can pre-cast one minute buffs before combat. I have never met a DM who always tells you when the next combat will be, and never has the bad guys run away, talk, activate something that takes time to deal with before you can get to them, or call in allies after combat is joined, however, so I certainly wouldn't count on never casting one minute buffs during combat. Similarly, if you have a DM who never gives you nasty magical effects that you want to dispel in combat, more injury than your LOH alone can cure, or any kind of curse or restorable condition that you want to remove during combat, then you'll never cast those in combat. But, again, it's not reasonable to assume that every DM avoids those conditions all the time. (The 'you can always pre-cast 1 minute buffs' sounds a LOT more like white-room theorycrafting than play experience, BTW)
I have never played D&D without someone wanting to be "the scout" and even if they fail to spot the enemy they are always about 30ft forward meaning that any character moving 30ft and attacking would be 60ft away from the paladin and would likely double move for their turn not getting a chance to attack. If your saying you never use scouts I am sure you have these problems.
I would also say it only takes 1 turn to cast such a buff then the 1-10 minute buff last the rest of the fight as a rule ...

The intent is that letting go of something requires no appreciable effort. But picking it up does.
"You can also interact with one object or feature of the environment for free, during either your move or your action." PHB p190 Example listed: • pick up a dropped axe
Scenario 1: Player characters are not engaged in combat they can cast the buff on the first turn even if engaged and as part of the action of casting that spell ... draw their weapon for opportunity attacks.
So even if they have Zero warning...How does that impact anything? This does not require warcaster.
Scenario 2: Weapon draw engaged in a fight they drop their weapon (which does not use their free action), cast a spell and Pickup their weapon as part of the action to cast the spell.
...How does that impact anything? This does not require warcaster.
Sure their are times when might want this as feature casting reaction spells like absorb elements and shield but paladins don't typically use any of those that I know of. (Did alittle research and oathbreaker has Hellish Rebuke but that one subclass doesn't seem enough to account for this being the #1 paladin feat). As a rule the other 2 aspects of warcaster are more useful:
1.You have advantage on Constitution saving throws that you make to maintain your concentration on a spell when you take damage.
- But Resilience (con) is better for paladins and does the same thing, so why is Warcaster the #1 pick instead of it? I mean I don't care I am just trying to make since of it.
2. When a hostile creature's movement provokes an opportunity attack from you, you can use your reaction to cast a spell at the creature, rather than making an opportunity attack. The spell must have a casting time of 1 action and must target only that creature.
- So I was thinking it was something to do with this but "Blinding smite" is the best use of this I can think of and you don't get it until level 13 I believe... so why are paladins taking Warcaster at level 4?
- These feature justifies the other like a cleric casting Sacred Flame using this reaction not wanting to drop their weapon to do so as a reaction would not let them pick it back up.
So if your an Oath Breaker Paladin with Hellish rebuke, expecting to play past level 13 and pick up Blinding smite... then this makes a bit more since, but that still doesn't seem to account for it being #1 for paladins. I would have expected something like great weapon master or something fun like actor... but warcaster on a paladin? Just seems weird to me.
Based on this post and a lot of others at this point, it seems like a paladin tax for not knowing you just pick up your weapon after you cast. I mean I get casters including clerics because of the opportunity attack with spell and advantage on concentration saves, the casting with a weapon usually only being useful to clearics but ... they all want the other 2. Its really surprising to me all the posts saying they are taking warcaster because they have weapon and a shield which seems like the lest useful aspect of the feat. Also, all those two handed weapon paladins just need to let go of the weapon with one hand and cast because they are just carrying the two-handed weapon with one hand (over their shoulder perhaps) and you only need two hands to wield it. Since any adult could realistically carry a 18lbs or less item in one hand for 6 seconds and carry weight would not change if your just holding it and not fighting with it, you might think two handed weapon paladins alone would make this feat less common than heavy weapon master that has comes in second by a 10% lead...
