Either it's new weaponry, or it's the ability to use global research and a boost to defenses. It's quite retarded that even keepers who have a far lesser equip than me, and thus can't even perk me w/o CiB up, who do not have an ounce of root resistance, not even free movement stims, can still choose to swap to an AS weapon and force me to run circles and use LoS, healing up.
Much worse is the huge stream of MR troxes fresh from ely kites, who can kill you as fast as a 220/30/70 keeper in the best possible setup, just because my perks can't be used reactively versus MR.
It takes away a good deal of the fun of PvP, and makes you annoyed as hell, that your billions and billions worth of equip (full CSS, ELLTS, the works) still means you can't compete with someone with half the experience and equipment.
PvP should reward time and thought invested into your setup / strategy / 'skill' (used loosely

) more than it should reward making the 'right' choice at character selection.
