lerk can be the most important creature if it does umbra,spore and primal scream right, he also focus bite jprs good, but gets pwned with 20 hmg bullets, spikes are funny on co servers (like sentinel) , but if u see ingame 4 idiots that only use fade to use acid, we will have all team lerk using "spike spamm",,,,
btw, gorge spike is not a good idea, wtf its a builder unit, if i get like 10 frags as gorge in some classic rounds, equiped with spikes it would be imposible to kill, imposible to take rooms wihtout losing a lot of marines on it,,, leave the poor fat as it is
