Shield level in PvP - what is the difference?

After doing level 7 or 8, i chose level 5 in PvP… you know, there are 10CP and other stuff…
Soo, i got my ass kicked in second fight (yeah, my champed OML died with rest of the team… awesome), promoted 5s and/or promoted + powered up 4s everywhere… what the hell is the difference between clearance levels… well, beside of the rewards?

What exactly is LB?

LB = leaderboard, aka bracket.

Set that aside, this is the most counter-intuitive thing in MPQ. You face the exact same group of people either you join SCL1 or SCL8.

Just as counter-intuitive as PVE was, thanks to roster-based scaling.

So, there’s hope yet.

What else should i expect?
Reaching 40 wins is impossible for me otherwise…
PvE wants less and give less… why should i expect something else from PvP, that obviously gives less, but demands the same power…
