Currently, even NCsoft (internal) shown a ratio of 6.2 (elyos) to 3.8 (asmo) at all times. But asmo are more active in seige and more geared player(at the moment). But since NC is planning to hand out free pvp gear to everyone, things would flip soon if elyo's pve hero also comes to seige or open pvp.
So any plan from NC on this? LFG on Asmo is much less active then elyos, it would take 50% more time to LFG anytime for asmo (even during peak hours).
