Most people are against it because it's a medieval mod and it's not realistic at all that in battles of 5 minutes length you are able to heal anything.
I'm ok with this, and i guess that's why it's intended (only) to Strategus, and this seems not necessarily realistic, but it goes into a game mechanics, as in sp, when you lose some tickets, they are only wounded, in this way, minor injuries (no loss of tickets) can be treated immediately.
It's like ladders, that give more possibility, new tactic, more gameplay.
