I've returned to the game recently and noticed the pvp scene has somewhat died due to arenas being the only form of competitive pvp available currently. And that solo que and group ranked pops are time specific and have ridiculous wait time at times.
My suggestion is the return of ranked pvp in the 8v8 format and allowing there to be strict time schedules to queue each day depending on the servers Time zone. (Example 2-10, Sat&Sun) Mon-Fri 4-9)). This stops foul play with the ranking and encourages more guilds to start participating.
p.s I would also like to add that during each season people who cannot participate in ranked battlegrounds should have a preset low mmr in regular battlegrounds that can go up during each season for lower rewards
p.s.s All reward tiers are given upon achieving the required rank and tertiary rewards are given at the end of the season for achieved ranking.
