If it has MW4 game play mechanics then I would say its going to be very boring.
From reading your posts it doesn't sound like you played very much or at all in FFP servers. Pop tarting was not a big issue in FFP servers like they were in 3rd person servers.
Another thing that made pop-tarting artificially good was Mw4's lack luster netcode. Mech would frequently not take damage correctly in the air.
MWLL is FFP, (and two cans and a string has a better netcode then MW4) so i'm not really worried...even if it was carbon copy of MW4.
Plus, like they said, BAs and Aerospace will molest stationary mechs in-love with their pet hill.
