I don't spend money on the game besides to buy crystals for war. So it is difficult to compete with LB players in round wars. So I stopped doing them. BFA is still used in non-round wars; do the indi wars.
Besides the fun of doing wars, devs need to provide incentive for more people to participate:
Equipment (the reason why people participate in the Season wars)
Mithril (the mith payout is a joke; this needs to be increased)
Gold (there's no gold incentive for warring; you lose gold (pots) by doing wars and not EB's)
EE level (this is the gold incentive)
Crystals (crystals cost money. people who can't afford to buy them, won't war)
I only do wars to keep my EE level from expiring (every 2 weeks), because between seasons, there is no other incentive. Even EE L1 is better than nothing. Indi wars are a coin toss. You have just as much risk to lose your EE level as gaining one.
If you want people to war more often, then let the EE level expire every 2 or 3 days, 1 level at a time.
And make it so you don't lose EE levels for warring and losing the war. People will war all the time to keep EE levels; just like people do the plunderless and painful EB's for the Blood Rains bonus.
