Always did, hence I didn't really think high caliber was necessary for them since I found them useful enough to get rid of those freaking steamships. I just assumed they had lower caliber so that punches would have a point.
Btw: Stonebinder is a terrible terrible class, please rebalance it.
Stone shot is obnoxiously weak. It's as weak as storm drone, except at least Draftlock can use clinging gust and completely ignore its primary spell. Using stone shot on an enemy walking casually towards you will very frequently fail to kill it before it hits you.
Stone charge, like all charge spells, is pointless because charging it doesn't result in a significantly larger projectile both sizewise nor caliberwise, you can't hold it for when you need it (it eventually autofires), the charged damage is pathetic, and charging the stupid thing for 5 seconds only to see it ping harmlessly off a crawler bug shot is aggravating. Charge spells are hopeless in their current incarnation. For them to be useful, they usually either 1) need to do damage while charging 2) need to pierce 3) need to grow significantly larger and more powerful enough to justify not shooting any other spell while charging, which equals a one (and two at the most) shot kill on most trivial enemies, not charging a stupid rock for 5 seconds and realising you need 4 more to kill an eel.
Stone fusilliade, like the other fusilliade spells, is largely a waste of a spell unless trying to kill idiotic robo spiders, because the damage actually manages to be worse than stone shot, which is quite a feat.
