Hi i'm new to the game and ended up buying cable as soon as I joined since hes one of my fave heroes.
I'm interested in basic information about the game such as the best way to lv and to spend my points.
I'm also looking for any end game gear i might need for cable.
Will tip for good info/ basic help.

There are many guides posted on the Cable subforum of the official Marvel Heroes forums: https://forums.marvelheroes.com/categories/cable

Best way to level is Midtown/Holo-Sim/X-Defense to level 25 and then do Legendary Quests from that point. You can reroll them to get quests in Midtown Manhattan and the terminals (go red once you are able to) [press L once you reach 25 to view/reroll legendary quests].
Shared quests are also a good form of getting XP and you can probably knock them out as you're doing legendary quests (you'll get reward chests from shared quests that will help you gear as well).
I think you can still claim the year anniversary loot, so hit level 30 ASAP and then accept the remote mission and talk to Agent Stan Lee in Avengers Tower to get a crapload of stuff.

You can do LQs at L20.

Thanks for all the info so far guys. Do people sell relics on here? If so how much per Wakanda Relic?Also what kind of insig would
I be looking for, for cable?

Relics cannot be traded.

Once you can get kinetic repulsion (the orb) and max psychic haze as you go. He is really easy to level up and once you hit 18 put 1 point into quick body slide and you're gold. End game look at maxing energy pulse/veteran warrior/vortex grenade/psychic haze AND barrier/repulsion and put 1 point into eye for weakness/bold aura/mental resilience and whatever else into barrage or whatever it's called. That's a basic Cable build. Gungnir for a legendary and lemuria for relic.
