All right lads. I have another .... question ?

As a "new" player (in DMM that is), what would be the best way to go about my business ? Currently I am lvl 24. Managed to get my Xmass event girl maxed out and equiped with the Xmass items (I have been focusing on that aspect pretty hard, as In the beginning every 5* is a big boost to your army).

Now I am trying to quickly get the Reissued event girl. I think there is like 9 and half more days to go, so getting her should be not impossible.
Though the fact my units are super weak and get annihilated rather fast is kinda problematic as well.

Now yes, maybe I should be running the standard mission maps as much as possible to grind up lvls, but then I am not sure if I can manage to get the Re-issue girl on time.
And heck It has been a rather long time since I was as weak as I currently am in FKG, so I kinda cannot 100% decide on my priorities.
I suppose, try to quickly get to lvl 30 or smthing, And then play the reissue with 5 days left might also be an option, hmm...
