Glad someone created a thread on the topic. I don't mind having to work hard to earn my next lvl, what concerns me is my ability to remain engaged in a game where a variety of methods for gaining xp is limited to running the same few maps repetitively. Repetition of the drab sewers is what fatigued me of PL. What I would ultimately like to see are alternatives to the typical limited number of maps if the grind will be more hardcore in SL. If SL will be more of a grind than PL, I hope at the very least there will be more maps included within future campaigns than the standard number. Otherwise, added repetition and stagnation in map variety could be a game killer.
