actually have sent in a couple of support tickets before. some of them didnt get replies >_>
one was asking for event extension in GK (previous event, last minute reward list), was ignored.
and I sent in a total of 3 tickets regarding KG's translation issues (Artemis -> Ultimus, Holy Scourge/HolyBanishment tl inconsistency, and can't remember what else.) Only received a reply that they will change it during dec 2015 update regarding Holy Scourge/Holybanishment tl inconsistency, but nothing done so far. and no reply for other 2 tickets.
