If you're playing in any mode besides ambush your supply depot access should be fine, but i do see your point about armor tankers. But, there was a post just above this one which added "and all active modules have refreshed". This would completely fix the idea that armor reppers could still recall because they would have to use an active module (that has a long cooldown time) before they could even begin the recall.

Consider how CCP handles the RDV simply dropping the vehicle, can you imagine their attempt at having it pick one up? And pilots DO NOT need to carry repair tools because all they have to do is sit next to a friendly supply depot, and SHABAM, their repaired very fast. The only mode this would limit pilots in is AMBUSH, and hey, isn't that a really good thing since people hate that vehicles plauge ambush? This would severely give them a disadvantage in ambush that infantry could use to their advantage.

A repair tool should honestly be a sound requirement for vehicle users that run shield, who also want the ability to recall whenever they want. And only in certain cases are supply depots hard to find, I'm not sure if you're aware of this or not, but I'm a veteran dropship pilot, and know the locations of all the supply depots on every map when I'm flying. There is ALWAYS one at your ground spawn behind the redline, therfore making it only occasionally neccecary for a armor repair tool for a shield tanker that's in trouble.

The entire purpose of this mechanic would be to stop recalls in combat situations, and that's the most common way the recall mechanic is abused.

If your infantry suit is at all anyway damaged and doesnt have all ammo on it and equipment you cannot swap at a depot

But it should be true

All vehicle have to have everything 100% perfect or we cant recall and thats the OP suggestion so why not do the same to infantry?
