Just wanted to leave some feedback about this achievement.
I’m a Horde main, but the BFA storylines have made me take an interest in the Alliance side of the story / game for the first time since the Wrathgate Scenario back in WOLK.
So, I duly levelled up my Alliance character and was really, really excited to start on the War Campaign and play the storylines through. I was then stonewalled big-time by the 7th Legion Rep-gating, which I’d forgotten existed. After being stonewalled the first time around (Honourbound Rep) when playing through the Horde War Campaign, I was disappointed (to say the least) at being stonewalled again. This sudden, enforced stop really took a lot of the fun out the story / process as well as the wind out of my sails and just seems redundant at this point in the game.
I think (not 100% sure) that the Two Sides to Ever Tale is the first achievement of it’s kind (correct me if I’m wrong) so I guess it’s understandable that there’s an element of trial and error, but I would argue that should there be future iterations of this achievement the second, equivale rep-grind / rep-gating should be removed if a player has completed everything on their character on the other faction. I’ve already ground out all the reps on my horde main, and it seems such a shame that a pretty pointless rep grind is all that’s stopping from enjoying the Alliance storylines.
