Tell me about it. So many times I've been accused of speed hacking, among other, simply because I use transcendence. Told the guy who keeps harassing me what the ability was, and how its even possible to use it back to back by getting fury naturally then through valorous call, but he refused to listen. While there is hacking in this game, a lot of people are wrongfully accused of it simply because someone sees something they perceive as hacking (transcendence, inspiration, popping all defensive in 1 single fight, self heals on a sentinel) which turns out to be a class or regular ability. Currently on beregren colony I'm being accused of speed hacking, damage mitigation hacking, cooldown hacking, and heal hacking.
Speed comes from trans. Covered that. Heals are the spec, watchman. For some reason these people are absolutely sure that sentinels can't heal. Damage mitigation hacking they call it: rebuke, saber ward, and a warzone adrenal I call it. I usually use this combo on the people who complain about me. ;D As far as my alleged "cooldown hacking", apparently I stealthed 5 times in under 10 seconds before. That one had me laughing for a while as not only I did i not do it, but I don't even see the point in doing that if I even was capable of doing it.
Like I said, there is hacking, but be absolutely sure that it isn't a class or spec, or regular ability being used. I'd hate for someone to have to go through the crap in warzones that I get just by being a good player. At least I can handle the critics, I have nothing to hide and have even adked CS reps to investigate me just to prove that I don't use hacks. Some others might not be so patient however, so try to be absolutely sure before accusing.
Let me get off my soap box now.
