This article has the most information about Mech5 Mercenaries that I have found and I was basing my opinions off of it:
http://www.pcgamer.com/mechwarrior-5/As far as 1st person vs. 3rd person:
I wish they would make a 3rd person option then have rooms for 1st and 3rd person like mw4. I've read repeatedly on youtube that some mech fans think the 'hill pop/sniping' is a bad playstyle in a mech game. I can definitely understand that perspective if you are looking for a realistic simulator mech game.
However, for me, I have my fun in online games by trying to out think other players. The reason I like 3rd person is because it makes the game less melee combat ("noob rushing/shooting at point blank) and more strategical (map positioning/flanking/using cover your see around your screen/etc.).
I explain what I mean here at 7:25 to 9:45

To me, I am more entertaining by strategy and thinking rather than repeated melee combat. It's that way in any game for me. I find creative thinking exciting and repetitive things like spamming overpowering game elements and noob rushing/repeated melee engagements boring.
Anyway, I read all of your replies. I like you being open minded. I am downloading MWO right now. My graphics card is an 8600 and min requirement is 8800 so I don't know if it will run, but I will see. I am going be open minded and see if this MWO game is any fun for me. I was wondering if I should record my first online game for laughs. It could be a funny thing to look back on. ::) ;D
