EA - Been there a dozen or so times.
5 year - not quite. Close a couple of times
One thing I'm reading that I think may be part of your challenge is it seems as though everyone is doing all the tier 1 modes, then to Kobi MB and then focusing on tier 2 missions. When I'm going for modes vs score I'll generally do the level 1 modes that correspond to the level 2 modes I struggle with first. I then make sure to get into that level 2 mode right before I start a MB. I actually prefer Klingon MB for PD2 as Klingon MB feeds the right lane which makes the warp shot easier. Vengence MB loops to the left lane. So basically, all my MB's are used playing Tier 2 missions. I stay away from STE2 and KB2 while in MB as those are fairly easy to complete in single ball play. For the most part you can just keep backhanding the left ramp until they are done with the occasional shot to the right ramp.
Also, if you can get to warp 9 quickly don't stop there trying to double your PF at just the right moment. Keep them flowing as at 9.9 you get an add a ball. Having that extra ball in play can help.
For me, the times that I get to EA seems to always be the times that I get to Kobi MB after I've already knocked out 3 or 4 tier 2 modes already. Works out nicely for the extra points as well for your trophies.
