If the point is that convalesence is useful to WAR's Thrill of Battle, then that's fine. Misunderstood the point of the post about surviving tankbusters.

Just note that its a variable eHP bonus that's limited in relation to the WAR's current HP. If you're already at full health when popping Thrill of Battle in prep for a tank buster (which... you should be), then Convalesence's bonus eHP is lost.
