Second Wind's stength comes from warrior mobility imo. If im second winding and no external heals are coming, I HL 40 yrds away and either intervene an ally or charge a critter or whatever or LOS and BAM im 70 yrds away regening.
What people fail to realize is that wars are the only class with absolutely 0 self-healing until second wind. That means you can play as bitch and as defensive as you need to because we will slowly drain to 35% with no way to stop it: so as a feral, apply bleeds and kite/bear. Then you whip out the burst and its gg.
