If it was easier on other platforms then it woulda be easier for
everyone on said platform...So you'd still have to be an accomplished player to stand out
There will always be differences in the way the game plays on pc or console (as you say) with the player count and differences with mouse and keyboard vs controller. However these differences won't necessarily make it easier (perhaps just a different 'feel'), so just because you are not particularly good on pc doesn't mean that xbox is easier, maybe you need a mouse and keyboard or a good squad of mates on pc. I play better when playing with a good squad that I can communicate with like the guys on here

Ps camping in a tank is a sign that the opposition need more engineers. Nothing to do with an easier platform.
