So lets talk about fire beetles...
The damage buff in the new patch is awesome! However, it's useless when they don't actually explode. It seems that they have a charge up before exploding, which makes them a very easy target and pretty useless against moving units.
Basically I built 5-6 fire beetles to fend off a GC (I wasn't going to make it so I thought why not? xD). Well I ended up with a couple of the fire beetles headbutting the GC's feet and doing no damage at all. If it was a target with equal or near walking speed I could understand, but a GC?
And yes I do know you have to tell them to attack the unit directly for them to explode, but that wasn't the problem here. They didn't explode until the GC stopped moving, so I'm guessing they have to "charge up." I'll have to do some more testing, but if Aeon have mercies can Cybran at least have a mobile bomb that works a little better? :'(
