Is it even possible to get a +experience trainer function for this game? I just want to get sure before I invest lifetime plus RC. Thank you in advance!
That's not really been feasable, but what you can do especially in earlier levels is do high level misions and use tarot cards to make the level higher and improve XP gains while using god mode and easy kills to breeze through it.
At higher levels it takes longer as xp gains reduce though. Pretty certain XP gains are controlled by the server rather than the client.
was the no reload ever fixed?
That option is a bit hit and miss (in my experience). The best advice I can give is to wait for the mission to load, wait for all intro voice overs to finish, and change to your alternate weapon and back. Wait for all the cooldowns on your abilities to finish, then try this option before any others.
Even then it may not work. Some days I've had it work the first time, others I could never get it to function properly no matter how many times I reloaded the game and trainer. It is what it is, I guess.
