A lot of hordes assuming that the exodus of the Alliance will not affect their ability to rank up because of bgs, but it wont work. If you want to reach high ranks as Horde on flamelash it will take significantly more efforts, if it’s possible at all and here is why:
First the queues, horde outnumbers the alliance and so even if the bgs are cross realm Horde will have longer queues which will probably be worsen by the Alliance having less pvp oriented players since most went horde for the racials. So a smaller percentage of alliance will bother with pvp, making queue times worse for Hordes.
The other issue is that the only good bg to farm honor is AV, WG is the land of premades. It’s a well known fact that people scout ahead before going in the WG to check if the ennemy team is a premade by only making one go in and they jus’t don’t join if it’s a premade, so it’s back to queue time. And knowing that the queue times will be long for horde they wont be able to afford skipping matches to avoid getting farmed by a premade abusing the fact that there is no timer on WG. And since AV need a raid on both side it means more Alliance required to actually queue for pvp and so even longer queues for Horde.
But how does that affect Flamelash Horde specifically ? Queue times will be a problem for all Hordes regardless of server. Yes, but Horde on over server can actually go wpvp while waiting in queue so they don’t have down time while farming honor and well, let’s just say it isn’t an option for Flamelash Horde.
Which lead to the final point, when trying to rank up you are not in competition with the ennemy faction but with your own faction as the amount of honor needed to rank up isn’t set in stone but based on what on the amount of honor over players in your faction farmed. Basically the more other people in your faction farmed honor, the more honor you need. Currently Flamelash is listed as large in population despite the Alliance basically left it, so almost everyone of those thousands of people are in direct competition with each other which could lead to very high amount of honor required to enter each bracket and makes coordinating between brackets more complicated.
If we assume a best case scenario where everyone coordinate perfectly to gain the exact same amount of honor per bracket so as to not inflate the honor required to get into the next RP bracket it would take twelves Week with the 20% weekly RP loss to get to rank 14. Now such perfect coordination never happens, and the envirronement that is Horde on flamelash will make it harder to coordinaate since they are just too many people so there will Always be people farming more honor to get ahead to the detriment of others, and with so many hordes the percentage of selfish people will increase. But even if we theorize that everything goes 100% perfect for Flamelash horde they are still floor of RP required to rank up. So the big question is: will there be a hard cap on how high a flamelash horde can go ? Meaning that even if you farm honor 24/7 it wont be enough to offset the honor weekly decrease to reach the RP floors to enter a new bracket. It’s impossible to know for sure as it will depend on how bad queue times are for horde since queue times are basically dead times on the honor farm, even someone on a pve realm is more likely to find regular wpvp than Hordes on flamelash at this point. Although this last point is really a worse case scenario and quite unlikely, although a soft cap is much more likely. Basically it’s technically possible to reach rank 14 but it would take so much time people wont be able to do it.
So yeah, bgs wont save flamelash Horde.
