KQ sucks. especially since we have Corp and whatnot. KQ was horrible in the old client, and I doubt Jack would spend much time on it. As for a Summoning guide, Jack doesnt make those, players do. You might do well in asking some veteran guide makers to make you a substantial one, or some random person/staff to give you the rundown. Once I get into Summoning I have no doubts ill make one, but as of yet I havent even touched the skill.
Obby maul is extremely slow, and isnt really useful. So no comment.
The shield thing DOES need to be fixed, but not an important issue as of now.
Hand cannon.. Only use I can see is for PKing, and.. Well no one ranges in PvP that I know of XD.
Onyx bolts aggreed. Only (e) though, and they have to work, and be extremely expensive XD.
Ghost armor.. No comment
Ancient Staff yes.
Same for Slayer Helm
