If we take all of these abilities which over lap a lot of the Thief and Monk abilities, I suggest decreasing HD to a d6 but keeping the same Fighter Atk, Saves, Weapons and Armour.
Warriors have high hit die to deal with being attacked far more
trying to defend the other guys according to Gygax... not because they
are flat footed sods in comparison to one spell. you think giving them
a single spell power is worth so much LOL see that proves the point
the wizard does it all without failure inspite of that being a ridiculous
mismatch for the flavor description of spell casting. The mechanics
were a horrible mismatch for the flavor.
And who said the ideas were just for fighters? These are martial abilities
A Paladin could have an ability to crash with his mount through enemy squares
without taking opportunity attacks and maybe even in epic punch holes in castle walls
protrayed with a glowing aura of divine energy instead of paltry low level priest magics.
You might have a Fighter w/ horsemanship aka Knight Cavelier to do the moving through enemy lines trick with nigh impossible mount control.
The Monk can definitely do the missile management and in flavor if you go with the damage dealer style might use deflection thing to harm adjacent enemies or have a once in a while roll well and catch and throw physical ones back. Are your monks jealous of the fighters sword and armor when he can do it without LoL.
The thief stole ability the original fighter had in the first place giving some back
and make him less lame in his own way he needs more battle field control abilities like hamstring enemies as he runs past them slowing a whole bunch and doing small damage and similar things to suit his style --- I think the rogue being big damage dealer wasnt the best design idea.
High level magic users in 1e also had just as good of armor class *Bracers of defense) as the fighters did after a certain level they only have slightly less in 4e. Rather like the spell armor in 3e.
How can we balance the Fly spell when the Fighter gets a Griffin mount? All the benefits of Fly plus extra attacks and it only costs gold and can be used the whole day.
The flight ritual should by that time only cost gold (and be used the whole day) dont you think
Addition that sounds like it might be around when the Wizard can become a Griffon? and suddenly able to do both flying and zoom into close range for nasty Melee?
Yes I am sure he will be jealous of the fighter or monk or whoever doing parkour and climbing the wall at running speed when he can teleport across the continent...
All of those abilities were just to keep minor parity with one bloody underestimated spell. And the abilities still do not match the fly spell they just get close
Mobility does not change one being a defender or striker or controller or buffer/debuffer - being mostly frontline for a defender and some striker vs being mostly second row for ranged controllers and some ranged strikers affects hit points.
