Disclaimer: This is my opinion.
I'm looking at you mr. hardcore pvp-er who isn't happy with the current state of the game.
From the threads I have read it would seem that the hardcore crowd is upset that this game requires no real tactics in PvP outside of zerging. Also and more importantly they are also upset with the fact that "stacking" to be a more effective zerg can no longer be defeated by 4 to 8 players. Thats so carebear of you guys...
Lets be honest guys/gals. You don't want difficult and challenging fights. You want to be able to smash everyone and look epic while doing it. You want to be able to poo on those bad zerg guilds with a better "build", more stats, better combos etc...
The truth of the matter is that, spending more time in the game to get the necessary stats via gear and vr to make pvp a trivial carebear "press my buttons in this order to win" ez mode, no longer works. You can be beat by shear numbers alone and now suddenly this game isn't fun for you. TYPICAL CAREBEAR COWDOOKIE!
Stop trying to ruin pvp with your carebear mindset and instead be the no life hardcore pvp-ers that you claim to be.
After the goal of this games only pvp mode is not to will other players. Its to hold keeps and steal elder scrolls. The zerg is powerful but it is stupid and predictable. Carebears want to wave their sunshine dust at the zerg and win. Not gonna happen...
My Advice? Use what tools ZOS has given you to outsmart the other players. Hit more than one base at once. See a zerg? Dismount and sneak by with your little 8 man shock troop. Even better, have someone scout out the battlefield (stealthily) and plan your movements and targets accordingly. Have you Night Blades Stealth Fear packs of the enemy to slow them down while they are attempting to regroup and zerg you. And finally stop being so carebear... haven't you ruined enough mmo's?
TLDR; READ IT! I Double dog dare you not to be a carebear and read this!
