Can i get banned for using ReShade ?
Nah, although I suggest checking gw2hook as it is a version of reshade made with gw2 in mind and the creator has worked with anet in the past to make sure it stays within the terms of service so people don't get banned for using it.
My list of suggestions for GW2
Akkebi | Akkebyyon | Alister Kebi | Akkebi Revi | Occultist Lulu | Shadow Stalker Lulu | Daddy Horrik | Glittermancer | The Mewcifer
Max Masteries | 15k AP
Thanks for the answers I made my own Reshade preset GW2Hook is based on older version of Reshade plus it have working AO and DOF these two things require depth buffer (by default it is disabled in online games) to work and i think this is where it conflicts with TOS
