If it isnt broken dont fix it
Its ridiculous that the daily challenges are randomized to potentially include combine ISO, world boss clear, or even ultimate world boss clear. These are challenges that a good portion of the player-base are unable to complete, which means they have no business being part of the daily missions. Hell, even the alliance battle daily affects players that arent in an alliance. People that pay money for the stark stash do it for a guaranteed 100 crystals a day, and now free to play players arent even guaranteed to get 25 a day.
Also the gear changes are awful, but I think the daily quests have a much larger impact on all players of the community regardless of progress.
