Since ticks have a ridiculous low rate for looting, plus the fact they do almost no damage makes the engineer specialization almost pointless. I think a vast improvement would be if engineers could also loot those ball mines that tanks use and program them to roll to the closest targets. Or at least let us roll them down a hill into the enemies. I think this would add a great deal to the fun factor of this skill.
And what about a chance of looting an exp. flamethrower from apoc hunters or throwable/deployable gas tanks with explosive gas from apoc harvesters?
