Artillery Ballista bugs

Artillery Ballista sometimes shoot 1 or 2 projectiles even I have +3 projectiles from talents/support gems. Increase qualiti of Artillery Ballista does not increas stats in stat info of the gem. Hence, "attack per second" or "Damage per second" is the same for all quality of the gem.

Moreover, gem info window sometimes jump automaticaly from window "Artillery" to window "Ballista". Maybe it is cause by ballista attacking.

This gem quality "x% increased attack speed" still doesn't work, the one without quality and the one with 20% quality have the same panel, dps, attacck time,etc.

The quality still doesn't seem to work. Doesn't change panel for attacks per second/damage per second and doesn't seem to have an affect on actual attack time of the totem at all either.

This bug still exists after all this time. Skill gem quality increase does not improve ballista damage stats. Another annoying bug is that ballistas despawn if you use your life or mana flask.

Encountered a strange bug where I can't use the skill, can't even map it, i have all the required stats and was using it just fine before entering the grim tangle, this kinda sucks cause it just bricked my build...
