Wow PKM dominates mg36? I seriously challenge that. Go check out my *very* long indepth review on
www.totalbf2.com including footage and screenshots of the 2. The pkm is more accurate if you fire 1 round at a time, then again so is the sniper rifle. If you want a true support gun grab the MG36, I don't play with anything else and I regularly score in the top 4 on my side (64man server).
The mg36 allows you to fire extremely accurate, fast supressive fire. Most people think the pkm is better because it has a slow rate of fire meaning it stays accurate longer in terms of seconds, plus it does more damage per round. This is flawed for 3 reasons:
1) It fires much slower than the mg36 which allows the mg36 to do almost 50% more damage in the same time frame.
2) They both have the exact same deviation per shot meaning they have the same accuracy. The reason the mg36 appears less accurate is because it fires much faster, meaning the deviation per shot is noticed sooner. However, shot per shot the 2 guns have the exact same accuracy.
3) The mg36 heats up MUCH slower than the pkm. The mg36 can fire off almost an entire clip without stopping before it overheats. Since support should fire in bursts (and the mg36 has burst mode so you can spam click and still get burst accuracy) the mg36 will never lock up, but the pkm will firing burst after burst rapidly
Anyways choose what you want but the mg36 is the pro support gun of choice while most new support players prefer the pkm because they try to fire it like a sniper rifle.
