No support from me-- The Springs are a prize for coming on to Res every day, a reward and a privilege.
I think they should stay as that, particularly since some of the prizes (like colour changes) can be very valuable and if you get high enough it would be quite easy to maintain at least a Tier 3 standing even if you were gone for weeks.
They would become less of an accomplishment and reward for your vigilance if it was made a hundred times easier to keep your spot, in my opinion.
What I consider a better alternative s Tier drops. Say you're in Tier 3 and you're gone for a day-- now you're in Tier 2. That way, you're not at rock bottom if you managed to climb to the top.
