- that the reward is too desirable and will become "the norm", and thus a punishment to those who don't do the daily and "miss out." - typical of CCP this will never be iterated or improved (or not fast enough) to reward activities other than PVE ratting. - that CCP didn't reward a generic all-inclusive activity like "activate a module in space" and instead is "forcing" everyone to PVE rats. - the reward is unfair to those who can't log in for whatever period. - it's ruining the economy (or specific items in the economy).
There's a 100+ page complaint thread from when they first announced the feature, and now that they've announced it for Tuesday, a few small threads are popping up in General Discussion, re-iterating the various points. Reddit had a couple threads too, yesterday when the announcement was made.
One thing that's unclear to me is whether this reward is per account or per character. I believe the idea was presented as per account originally, but the announcement seems to say it's per character that performs the activity. Guess I'll have to wait and see.
