i believe you can get up to 50% troops back free nothing to complain about there i love the sick bay
That is only if your troops got killed in your base.
You will get nothing back for free if your troops died when you tried to liberate someone else, attack someone else, or got attacked while defending someone else, getting attacked while defending HQ, or getting attacked at repository, depots or mining complex. In all these situations you pay for troops recovery.
It would help the weakest. but at the same time it reinforces those who have no problem spending. the situation only improves, because the weaker player does not give in to the temptation to abandon the game, but perhaps if the cost of recovery from the infirmary is lower, he would be tempted to spend something more to get his troops back.
