I’m F2P, been playing since October.
I avoided PVP at first and focused on PVE. When my 2* were maxed and I started transitioning to 3*, I would only get to about 300 in PVP before hitting a wall of characters I couldn’t beat. That is fine, it gets you an event token and if you do about 300 in each PVP and push to 1K in Shield Simulator you should have no problem hitting the 4K for the 10 pack for the season… it will take you right up to the end that way… but once you hit that, you know you can push a little further next Season. I did find that as an early transitioner, I did find easier teams to beat and hit my 300 points by joining early. When I joined later, there were more people, but also bigger teams.
Pushing to a little over 300 each PVP allowed me to also play my normal grind in PVE since it didn’t take too many health packs to hit 300.
Next Season go for 500 each PVP, and you will begin to get the feel for where you are at, who you can beat, and how far you can push with the Health Packs you have.
If you spend HP, as was said before, Roster Slots, Roster Slots, Roster Slots… you will have your 3* in your inventory for a long time building up. Also once you start getting a bit higher in PVP, and you want to have higher Season score so you can merc yourself out at the end of the season to a decent Alliance (and if they like you they might ask you to stick around) you may want to spend a little bit on shields. This is when I switched to starting PVP late, so I can do one big climb between 2-7 hours before PVP slice ends and then shield when i’m out of health packs or when I start getting hit faster than I can climb. If you hit 800 and have your cover, you can throw an 8 hour shield and stay till the end… or you can throw a 3 hour and try to shield hop a little bit later.
Once you are in a good alliance, and hitting 800 regularly, and you now have more required covers for DDQ, your progress will speed up dramatically… you may even decide that PVE is just not for you anymore unless the rewards are a new character or the elusive cover you haven’t been able to get anywhere.
I’ve never bought a cover, but from what people here on the forums say, only buy the covers you need, when it’s the elusive last one to spec your vital character out.
