I ran THF setups myself for it, but we still took BLU for 2 reasons, if someone wasn't geared enough or was late on the rudra coordination then you get adds. If adds spawn, BLU takes care of them quickly and for most hte player base the adds would and did spawn so BLU was very used for this reason. The other reason is BLU is one of if not the best cleaver in the game so getting your KI again was super fast.
Some people are taking 2 BLU DD to everything and in alliances 3-4 on hard content but I never said everyone. Leaving out the reasons for above for example is leaving out context. Most people were not able to kill the Roc in less than 30 seconds so adds became a problem -> if adds spawned then BLU can deal with all of them very quickly. This is also just a single example, and I've shown I think on every point where my statements come from with context and examples. To me this isn't even a debate, it's just obvious proof from multiple people, vs deniers using logical fallacies to deny harder. It's pretty clear where BLU power balance, and population as a result, stand. I'd be glad if the next patch just nerf's blu already so we can move on.
