Depends on what you want from the game to win or just to play for points and kills.There is a lot of players who could care less about winning and just play for points.I like to win myself or more so .... I hate to loose.Players should have fun and people will play how they want.I never try to dictate how other people play.
The good players get decant KDR while being in the capzone helping their team.Minus mg and snipers they are the exception but even they should be supporting the objective in some way.What gets me is assault and riflemen who barely leave the spawn thinking their 20 kills will win the match
.
It is stupid seeing whole squads charge the same arty over and over.Or getting killed by the SAME mg 5 times in a row.Then again its lame to get locked out because your team refuses to push the cap for fear of death.Or getting bum rushed because only 3 guys is brave enough to enter the cap on defense.It goes both ways and can be frustrating
This is not a death match game and round can be won by playing for the objectives.More often this is what wins matches in TE simply getting more bodies in the cap.With good teams aggressive capzone type tactics will beat KDR any day. Using team work proper smoke ,arty and support so your grunts can safely get in the objective.
Reinforcements mean nothing if you steam roll the map taking all objectives while the other team ignores caps and camps.Or getting bum rushed or locked out with the timer by leaving the caps empty.Ignore the capzone loose the match its that simple.
Flanking and blocking is important but a single smoke can block your line of sight.Letting the enemy reach the empty zone so you still need bodies in the cap if you want to win.Most of the really serious KDR players never enter an objective... to risky they may die ...this is the flaw in their tactic
IMO it takes a combination of both tactics to be effective.Knowing when to be aggressive and when to play safe.Watching reinforcement counts and timer all factor in on how you should play.At the start of a round I will be aggressive if we start loosing on reinforcements I will start playing safer.If we have a huge lead on reinforcements I'm really aggressive.If the enemy has the huge lead I will play cowardly and only worry about KDR (depending on the time remaining)
My point being both styles are bad in extreme you have to have awareness to know when to charge and when to play safe to be really effective.
If you really are supporting your teams effort by covering or entering the objective KDR all you want I have np with that.If your a assault or rifleman and have not left the spawn .... You better have 100 kills because.... your class should be supporting the objective if you want to win.
