Been playing Paragon for a year+...I am NOT a hardcore FPS gamer, enjoy them, but suck at them.
Paragon is a mix of players who are good at FPS games (rangers in game), good at playing a support role in a team based fight...good at your squishy ranged/magic user/spell caster attackers.
This is the MOBA for people who are like me, good strategic thinker who doesn't have the best aim. (I use melee heroes and support heroes).
It's fun, gameplay is easy to figure out, but strategy has a long learning curve, and no tutorial. But after you take your lumps, and learn why you shouldn't push up a lane solo...it gets to be really fun.
Just keep in mind, this is NOT Call of Duty. No matter how good of a shot you are...you will get smashed if you try to take on multiple heroes solo.
The heroes are a blast too, and aren't cartoon'y like you see with many games. I'm just too old to play games that look like the people at Looney Toons create the heroes. (Overwatch, Gigantic, WoW, etc)
