I agree, it is very strange that Tristana ends the game with more health than Rammus, Singed and Amumu...and only a a few points lower than Malphite.
It is even worse with the melee DPS champs. Warwick, Tryndamere, Yi and Jax all get a ton of health.
The only tanks with really good health/growth are Sion, Alistar and Nasus.
