If I may widen my wishes beyond what I believe 5E will ever get us...:
- a "tanking" fighter subclass. A subclass that actually can influence enemies targetting (read "force them to target the fighter"). This subclass does not need to "come into its own" until, say, 5th level at the earliest: at low levels, 5E characters simply do not have enough hit points to work as tanks; remember, the idea is for this character to draw in lots of enemies. He needs a lot of hit points if the Cleric's job shouldn't become impossible. This subclass should probably have the ability to turn a "save or die" effect into a straight hit point loss (since the party will probably be close to a TPK if the tank falls).
- a controller fighter subclass; a subclass that completely disregards the current balance between martial (sub)classes, and provides us with a fighter subclass with 4E levels of ability to affect multiple enemies (bunch them together, whirlwhind them, hurl them away etc). This subclass should not and cannot be balanced against the Champion or Battle Master; the explicit aim is to allow martial non-magical characters a greater level of battlefield control while still not playing in the same league as high level spellcasters. Specifically, this class is not expected to replace or obsolete a Cleric or Wizard in any way, it is only meant for those groups who loved the way martials played in 4E; groups who don't subscribe to the current "high-level fighters are supposed to just whack people just harder than low-level fighters" and "if you don't like being simple, learn to cast spells" philosophies permeating 5E.
- possibly a Rogue subclass to complement the controller fighter subclass above; this pair is meant to be coupled with regular Wizards and Clerics, not regular Fighters and Rogues
- At least one "martial controller" class. A class that is completely and utterly non-magical, and still can both heal and buff party members as well as apply a modicum of battlefield control. The primary design goal for this class should be to allow for completely mundane parties that doesn't need to rely on magical items in any way, including "no healing potions".
That would be good
