Feats are the fighters class features. And he has more then enough. That gives him versatility (in combat at least).
No. Just ... no. In a different system, this might true, but no option that the Fighter has access to matches that of a good 4th level spell. The best third and second level spells also beat out the fighter in terms of battlefield control and utility.
Thats due to bad design on WotC's part. And its really obvious in high level games. The fighter is completely dependent on gear and buffs from his party. But most summons outperform him, and as Veekie said, "Ever see a Rogue in Hydra form flank?.
We can say, yes its a team game, so lets just let the fighter PC do its thing ... except its a similar to situations where a special needs child is put in the same setting with average kids; it becomes restrictive for the norms, and very dependant on how 'nice' said kids are. Rarely do people like holding back so a less able person does not feel diminished.
Its worse in D&D. If your character brings very little to the table, or can't perform at the same level as other PCs, you either become an onlooker or a liability if you insist on entering combat and dying/almost dying frequently.
And thats why the class keeps getting fixes so often.
