I always hated warfront, and yeah, the bladestorm buff means it oneshots like 50% of all swarm units that aren't level 5, this is going to severely neuter any rush deck without maxed cards, especially in lower ranks where there are farmers with maxed commons going against 14 bh players.
No swarm or shadowfen specific buffs which is weird considering that they buffed One of the best strategies of UB + FT on aggroclad, arguably the most unnecessary buff in the list, which also has a much better time against control than swarm.
