In MP combat missions I have never seen a Gazelle pilot do crazy unrealistic stuff. Everyone flies the gazelle more or less realistic.
What I see very often in MP is that Huey pilots flying way beyond the engine overheat limits (full speed at full loadout etc...).
Huey is long time out of beta and still has is issues while Gazelle has multicrew and is still WIP.
At least patience is needed in this forum section here. ;)
