Yeah those Hitmarkers ( X-shaped lines and sometimes a white/red cross) need to be removed. They appear when you just hit someone or even when you hit & don't see him and he's standing behind a wall:
Also, are there any hitboxes? I recognized that if you shoot someone in the head, even if you're standing in front of him, he doesn't get killed - no matter what weapon you use. At the moment only the shotgun seems to be the weapon who can do a 'one-hit-kill'.
I agree with the classes: Rifleman and Ranger should be one class (with selectable primary weapon). The same with CovertOps and SpecOps. Recon and Marksman could be joined in another class ("Special" or something like that).
And the regaining health feature should be removed. It works on CoD but not on TC. If you get shot you quickly jump in some corner just to heal. After that you can go on try to kill the enemy... he has no advantage of shooting you first...
I catched myself using this method all the time... it's more seek and hide than shooting back at the moment.
The smoke grenade needs a fix, too. You throw it, smoke appears and after 10 second it suddenly disappears. In that short time you can barely run through the smoke. The smoke needs to stay 30 seconds or more to be useful...
