MWO advice from a cadet newb... and new mechs/tactics are tried... just what n00bs and vets love...
I love the archer(gladiator). I have both the tempest and jaime now. And believe it or not, i do not run lrms on either.
I am sticking with the group (PUG). I am jockeying for positioning(s) as best i can. I'm equiping ecm (yes, i know it's not an unvulnerable umbrella) and ams to help everyone around me. But it usually ends up in either a f2f brawl that i just overheat and die in (yes, i know i can override that), or a map that my team just gets sniped to death in.
So, the experience gap is still noticable.
I get it, knowledge is power. I come from other old(er) games where experience beats exuberance every time (Planetside 1&2, WoW, =v= online). You don't just jump in and win.
Enter the new mechs and tactics.... Roughneck Bolt and Marauder(zentradi officer pod) Blight.
Roughneck Bolt: THE BEST VIDEOGAME NPC IN THE GAME. BAR NONE. [Better off Dead ]"Go(shoot) that way, really fast(accurately). If something gets in your way(or shoots back), turn." [/Better off Dead]. 4x ac of some sort and a shit ton of ammo for [Goodfellas] "F U PAY ME" [/Goodfellas] play. Can easily upgrade from there depending on your level of caring.
Marauder Blight: Feel like being a little bit more involved and not dieing because of late drops, lack of teamwork (understandale in PUGs), and same team afk'ers (or even TK'ers)? This is your mech. Can do what the roughneck bolt can do, but better.
So, as a cadet newb, to other cadet newbs, or people that just need to be reminded, instead of getting frustrated, go back to basics and start small. Or, if you prefer, to quote Harry Callahan, "A man's got to know his limitations."
The roughneck bolt (re)taught me to concentrate on the basics. Positioning, aiming, and info. The marauder blight has (re)taught me integration of the above with further simple weapon progression.
If you are new, or are getting burned out, try going back to the basics. It's SUPER easy to get lost in the weeds or stuck in a rut. Build a bare bones basic mech and try again.
It might just surprise you.
