For mostly-casters, I don't think its a good idea since you miss out on precious high level spell slots. Having said that, a pal2/sorc18 is pretty compelling. Heavy-armor-wearing, martial-weapon-wielding, smiting machine!
All I'll say is do what you want to do, there's certainly no wrong way plus in the end isn't it for fun? Oh the things I can do...ridiculous!
We always go all the way.What proportion of poeple get characters to level 15? I've played D&D since the early 80s and never seen a campaign last that long. All high-level play I've seen or been involved in, the characters were created at that level.
Characters concept. I have a pair of characters right now, who are a pirate captain and his first mate. The captain is a Warlock of Davy jones/Swashbuckler, while the first mate is a monk/swashbuckler. Both excellent for the Pirate aesthetic I wanted.
From the mechanical side, it depends on the concept. A bladelock, for example, is fairly weak to start off. However, Swashbuckler is a Charisma based melee fighter, making the captain quite good in close quarters. The Monk is a Dex based fighter, which also combos well with Swashbuckler. Both are going to be getting sneak attack a lot, and be fairly competent in solo fights.
It also depends on the class abilities you are missing out on. I personally don't need the high level Swashbuckler abilities, since they are less "Pirate fighting" focused, which is the only reason I grabbed Swashbuckler over fighter. I am then thinking of taking the captain to level 3 fighter for Eldritch Knight, which will give him the ability to always be armed with a pair of weapons. The Monk will be going to fighter 3 as well, for Champion.
All mechanics that lend themselves to my Character goals

How would you multiclass a necromancer?
I take to Multiclassing like a junkie to the needle. Inevitably my Character Concepts seem to demand it. My last PC was a Ftr 2/Wiz (EK) 6 (High Elf) when we ended. I'm now playing a Ranger 3 (Human) and (with the OK from a very lenient DM) I'll be "dying" and then "reborn" as an Aasimar Paladin. Very excited about all of this, to say the least!
