I havet read all the postings on the issue of warehousing, but i'll add my 2 cents anyways.
As far as I understand the idea of the MLD, its to be a realistic as possible, and warehousing seems to go against the spirit of this. It's like putting Lemiux or Orr in carbonite like Han Solo when they reach their peak only to defrost them for a playoff run, only to put them in carbonite again. Not very realistic.
I have used this practice too, I'd be stupid not to, but it just doesn't seem right. I know its a sim, and is a managerial tool for this virtual sport, and it doesn't really give anyone an advantage because we can all do it if we chose.
But it does seem to go against the grain of the MLD idea, so on that point I would vote to ban it.
Perhaps a phasing out. Next year only 4 warehoused players, the year after 2, then kaput.
viva la polka!
