well i love open world pvp and i love warzones as well.
illum needs a few fixes, for sure. I play emp myself and hate just zerging the spawns.
i used to play WAR as well and it was great pvp wise.
If you where outnumberd you got an AAO (against all odd's) buff with gave you increased bonusses from kill's to such an extend that i went looking for outnumbered zones for the increased reward. right now in illum its exactly the other way around if you have more players you control more BO's hence more valor bonus.
that combined with the fact that there are nearly no roaming party's and its mostly one big zerg at central assault (because of those useless armament's for the illum daily), its nearly impossible to get even one kill before being overrun.
I say implement a zone lock for controlling all BO's that reset like every 30 min's or so and give you a one time valor bump (say 1600 valor thats increased by AAO and removing the valor from controlling more bo's ofc). This will also spread the larger faction over the multiple bo's to keep owning them for the lock bonus, thus making it easier for the outnumberd faction to get kill's against small parties rather than being zerged all the time.
keep player kill valor bonusses at controlled bo's, only at a greatly reduced amout (lets say max 40 bonus valor per kill) and give the outnumbered faction an incentive (AAO like in war). And put up armament's at all the BO's to add to the smaller parties and give the outnumberd faction a chance to finish their daily's faster.
