Though, if you're getting average HP per level (as you're statistically likely to get through rolling, anyway), +2 HP per level is a 40% increase from the average d10 result of 5 per level. Almost half-again as tough as normal. So on average......+2hp/level is a good deal.
Most "melee fighter types" tend to have Cons of at least 14 and higher at higher levels (and D10 PC fighter types get 10 at first level), so +2 tends to be closer to a 20% increase than a 40% one over the long haul for most average PCs of these type.
