I am writing as someone who is completely terrible at MP, jsyk.
I always liked preferred playing napoleonic wars as i felt it simplified the combat for me, only ever up or down. Unless of course I came across someone with a sword, then I knew I was f'ed.
And when I played BL MP, I of course did quite badly. Whether that was my bad internet or bad skills, it doesn't matter too much. What I do know is that all aspects of the game, including MP, is still a work in progress. I am quite interested to try MP now since the 1.5.0 update because it changed alot of things, but even I know that if I am still bad it's mostly gonna be on me.
I know that unless they add autoblock to MP (which TW would never do) I will forever be trash at MP, unless of course I make at concerted effort to get better at learning how fighting works. It would be silly to lean on my age as an excuse (seeing as I am only 25), as I have been shown people in their late 30's to be WAY better than me.
I think it comes a point for most people where they must realise that they are just incompatible with the meta gaming a certain game's MP presents and that other games will give them what they want. I learned that playing altis life on Arma 3 or PW on warband, I just enjoyed roleplaying alot more than skilled combat. There is no shame in this.
