The sun pot change was one of the worst tweaks to happen recently imo. You take a spanking, go to hammer suns to stay alive only to find you can only use one per second. If youre still in the midst of a mass fight taking a lot of agro that can easily mean instant death. So it's no wonder these 'gods' are falling - not because they were using anything they shouldn't but because all of a sudden a crucial survival tactic has been removed. Same goes for PvE - some bosses have now been made impossible unless youre in a group of 25.
My understanding is that it was removed because of rumours about an AutoHotKey macro that automatically sunnies when youre low. To my knowledge, AHK is just a macro writing program and isnt able to do things like checking memory values etc so at the very best would be able to spam suns/a certain key at the command of the user, but wouldnt be able to automatically sun/rt/tt whenever the user got low. That sort of thing would require memory checking/hacking which is an entirely different thing. I'm no expert but that's my layman's understanding of things.
Happy to be proven wrong ofc.
