This may sound like a rant, or just me complaining, but I have found a few things that seem.. clunky or odd.

1) Arcanist spells: Bio and Virus. Both are instant cast, yet Bio triggers a global cool down, yet Virus doesn't. What's the sense making it instant (besides casting while walking) if it triggers the cool down? I'm sure this applies to other classes and their spells too.

2) Targeting: Tab-targeting can target creatures nearly behind you, 40y away, etc.. nearly everywhere you don't want to tab-target to.. instead of focusing on the enemy in front of you. I have changed the targeting under the Character Configuration panel and it still doesn't seem to work well.
