I know what you mean, on the BG server we have sometimes to deal with so called Rambo medics. Mostly they just like to frag and dont care about anything else. But at hte other hand , I see it as a good practice and maybe TM should change the name of the server.?
My last clan we dealed with the issue by making the inteval with the healthpackages bigger, so Rambo medics had to deal with waiting longer to get full health, but the disadvantage is, "normal"medics have to deal with it also.
