Instead of removing fighter assist, why not create a highslot module called a Fighter Assist Link. This module would allow a certain amount of bandwidth of fighters and bombers to be assigned. They could come in a variety of sizes so small ships might only be able to have 1 fighter assisted to it, while a large one could have several bombers assigned to it.

The problem isn't caused by fighter assist. The problem is caused by the decision to let fighters benefit from drone mods. Before this, unbonused fighters assigned to small ships were good for exactly one thing" shooting POS guns. and that's it. Fighter Assist is one of the cooler game mechanics EVE has and removing it because some people abused the gift you guys gave them is a terrible idea.

A better idea would be to say "you can assign fighters, but they get no boost at all from carrier bonuses, drone mods or carrier pilot skills".

As for the warp drive, yea, that's complete overkill. It kills the Carrier for fighter based PVE (a ratting of lvl 5 carrier would be risking 200 mil worth of fighters every site if they had to get out quick, or risk being tackled if they wait for the fighters). End result will be some who switch back to Sentries for pve, but others will stop using carriers all together (especially those who switch to sentries, after a few carrier losses, carriers aren't cheap).

This means more people shifting to afktars and the like for isking which is way less interesting content wise, some of the best fights you can get is when a carrier gets tackled in an anom because he got pointed by an npc at the right moment or misclciked and lost alignment , and for them to be out there to be tackled people have to want to use them.
