There is a trend on the forums to only point out the fights that are lopsided or unfair in one way or another. Have we ever tried to establish which fights are actually fair and balanced? Not just one-on-one either, although they would certainly be the majority, but even groups that can properly counter each other.
Rather than looking for factual accuracy, how about we just discuss our experiences with fair fights, or one's we felt were balanced. Including all levels and not just 220 is good as well, since I would primarily focus on the pre-220 aspects of PVP as well. Assume actual PVP setups or gear, unless you have a specific PVE setup that resulted in a balanced encounter.
168-174 ranged adventurer vs 168-174 fixer.
I had many fights with fixers and more or less they were drawn out fights that relied on timing of what perks could land and a slight reliance on luck with procs and specials. Both could win at any time, but a better player would tend to win more often. NCU crash/PO could offset the fight a bit, but bio cocoon was the typical counter if a fixer actually landed it.
75 MP vs 75 NT/74 MP vs 74 NT
Surprisingly a profession with NSD having an incredibly long fight against a casting reliant profession does occur. NT's have high NR which counters NSD landing quite well. The NT can also debuff the MP to prevent it from being used, meaning the MP would be relying on dominates and mind quake or a lesser nuke instead. Besides resisting much of the overwhelming casting power an MP can produce, NSII allows them to buffer the high damage from nukes and emnity until the NT mezzes the pets.
The result is an MP usually having moderate weapon damage and lower nukes trying to eat through an NT's health and absorbs without running out of nano, which will happen if the MP is not careful. The NTs damage is actually lower, so the fight is determined by the NT's ability to survive until the MP can no longer fight.
