There was a story I heard before in Ari that there is this one guild who almost if not all own all important OPs and it was also stated in that story that they attacked both Kami and Kara OPs. Basing from that story this guild is always out numbered in OP battles yet they succeded in almost OP battles. Even the CSR, I'm not sure if this is true is asking that guild to distribute their OPs.
Success of the guild you are referring to has nothing to do with them being pro at OP battles. First, they had LOTS of healing alts. Someone claimed they had over 90 accounts while there were about 30 actual players. Second, and most important part, that guild actively used (and they admitted that) third party software, allowing them to manage multiple characters at once, which granted them advantage in battles other players couldn't compete with. I believe changes in official policy concerning use of alts, namely prohibition of third party software and multiple alts at OP battles and boss hunts, were made after owners became aware of this situation.
We want fun greats wars. OP battle can't do it now. A 20vs20 is never seen in Arena, seems you are rookie to say this stuff.
Actually on Arispotle there used to be a couple of PvP tournaments at Arena with rules, prizes and such. Also there was regular event - battle over L50 Outpost near FH, with two proxy guilds declaring on each other. Everyone could come and join either side to fight for fun and giggles. Guilds and faction alignments didn't matter, people fought over useless OP just to have fun. It seems exactly like what you ask for.
Our tactics are fine. Really, they don't need improvements? For instance last OP, I don't reveal all, but we were 25 against 80. And we had like 6 healers. So we had 19 people to crush 80, it's impossible.
I agreed. Every time someone mention that some guild or faction won because of awesome tactics, i laugh. Pile in as much 250's as you can, add a bunch of launchers, that's all you need. Yeah, right. Tactics own.
Say, we have Side A - 100 players with team of launchers, and Side B - 50 players, no launchers. Say, all stats, gear and levels of characters are equal. NPC guards are non-factor. Please, Virg, enlighten me, i'm dying to know what tactic should use Side B to beat Side A in this given situation? Except for common tricks, like multiple attacks, aggro dragging, aggressing tribes and such.
