I've started to see the games become more pitched and interesting, but found a really annoying tactic. Its very similar to how people would camp their spawn in SA but this time they camp one of the forward repair bases. IE say the clan team has the forward base and is pushing up they engage IS forces but then as soon as they take damage they(very quickly) run back and repair at their bay. Then once the repairs are complete they run up and hit the still damaged IS forces. Now this wouldn't be a problem if the bay was 1k away, but the base is usually less then a few hundred meters away.
Also, say your trying to take a base, you get caught in a duel with another mech of equal class. During the course of the fight you both sustain heavy damage, and then your opponent runs into his mech bay and repairs. This usually happens with starter mechs, but if you follow them in and attempt to take them down its almost pointless. You can't bring out enough fire power to counter the repairs.
