If you're bored with grind all these new alts, why do you do it?
Seriously. Wouldn't a reassigning of attributes be more practical solution for testing? You spend time in leveling a single char, you convert your time in XP. Once a month, you are allowed to fill out a request to reset your char. You use the "online" function to submit your name and XP to a GM, delete your char and let him dig some ultrashits with your new character to gain XP.
You need alts for everything.
I need an alt for the best possible way to aquire a certain item, for example, I could farm VC patrols with a PVE farmer to get 5mm AP from their AR ladies, but then I would have to farm for hours or even days to get a decent amount.
Meanwhile I can level up a thief, have some boring levelling but be able to get my own 5mm without much problems later.
This goes for every single farmable item in this game.
And when it comes to PVP you don't want to leave early, you want to be there when everyone is looting the dead.
