I think you need to read the battlemaster again. Because there are maneuvers that grant allies an attack and a way to grant hp as well. And then you've also got feats like Inspiring Leader which grant HP as well. All of these are martial forms of granting HP.
Just because it doesn't mirror 4e, or doesn't fit your personal expectations, doesn't mean they don't exist. They absolutely do.
ok let me try again, maybe you didn't read what you responded too..
yes there is very limited commander strike at level 3 you get 4 uses of any maneuver per day, but can refresh if you take an hour off. at levels 7 and 15 you get one more use...
Commander’s Strike. When you take the Attack action on your turn, you can forgo one of your attacks and use a bonus action to direct one of your companions to strike. When you do so, choose a friendly creature who can see or hear you and expend one superiority die. That creature can immediately use its reaction to make one weapon attack, adding the superiority die to the attack’s damage roll.
so it costs you an attack (witch does mean at level 5+ you still get your own attacks) and a bonus action and costs your ally a reaction... how much would it break the game to make that (already cost 3 thing) at will... but instead you must spend 1 of 4,5,or6 superiority dice... you can't see a difference here?
in 4e I had at 1st level the following options:
basic attack
2/encounter heal target 1/4hp+1d6hp
Wolf pack tactics (Make an attack and me or an ally move)
Commander strike (Grant an extra attack to an ally
Warlord's strike (attack then grant ally's bonus to hit target till my next action) 1/encounter
Leading the Assualt (Attack grants ally's bonus to hit until end of encounter)1/day
in 5e at 3rd level I have the following options:
basic attack
commander strike (As above)
rally (spend a superiority die to grant temp hp equal to 1d8+cha mod)
maneuvering assault (a lot like wolf pack tactics but costs a die)
all 3 of the special options cost a resource that only comes back with an hour rest...
so with 3 extra levels, the 5e version has less options, and can use them less often...
I am not saying *You can in no way do x ever"
what I am saying is "You are less effective and way more costly to use abilities and I fear that may cause some problem with game balance."
