I voted both for yes and no.
No:
We grind/farm in PvE so we can try to do better in PvP. The game in itself lacks a good PvP scene/area that isn't the arena. PK channel, while it's been "overhauled," it's lackluster to say the least. Even with the changes made to it, there really is no incentive to be on the channel. Pop prems, then roam around the land for 1hr and maybe find 1,2 or 3 ppl? complete waste. I know, I get it, prems are optional but when you're trying to gauge or min/max your gear to be potentially be ready for any scenario you can think of they come in handy. Plus, they're in the game for a reason, no? As of right now, Siege provides this area/arena for players to do all of the above. To showcase that your PvE grinding/farming has paid off, somewhat at least.
Yes:
If it were up to me, I would love to see something similar to that of the Mission war /Nation war that Cabal Online has/had. capture the flag style. Level mattered a bit, it determined what bracket you were going to participate in. All brackets happened at the same time. Wars ocurred multiple times a day every 3 hours apart starting 6am EST ending 3am EST. The important war happened on Saturdays in the highest bracket, winning faction would receieve a Bonus war buff for 7 days. Bonus exp/ drop rate/ skill exp for a week. Gear wise: killing mobs/ppl in the arena would drop specific weapons which gave amazing stats to help even out the playing field. While the weapons were optional to equip, anyone who could get their hands on them would use them. I would love to see pvp mode(s) that even out the playing field and allows everyone to participate regardless of their gear, guild, level and above all prems. Would prefer it if said mode was not locked to 1 day a week at a certain time and not guild locked.
