After intricately dissecting the class and understanding the match ups, I do not think Spellbreaker is over powered. Actually, I think that it is much weaker than core war in every way. The main problem with the builds is that Spellbreaker's damage and overall effectiveness is based on momentum, and core warrior is based on clutch. The bad thing about Spellbreaker's momentum based play is that the momentum of the class is largely based on its enemy. As a Spellbreaker, if you can get your enemy to trigger your full counter and eat the damage, you are being more effective over all. As a core warrior, all you have to do is focus on doing damage, dodging, and stunning. This momentum based play also translates to the healing output by each build. If, as a Spellbreaker, you are not able to spam your full counter and burst skill, you will not build up adrenal health stacks, making it very easy to gain momentum against you (surprisingly, even berserker is better at maintaining the stacks of adrenal due to the high range of skills and the low cast times/cooldowns. Of course berserker is still worse due to lack of fluidity in gameplay that spellbreaker has). Even if you are able to proc it a decent amount of times to maintain the three stacks core war has up virtually 90% of the time, it will slowly drop to two, then one, if not refilled. Based on my experience dueling Spellbreakers on my core warrior, very VERY few are able to keep up. Near higher end play against classes that lack aoe's/adds, Spellbreaker doesn't make the cut. This is just my opinion, what do you guys think?
