Definitely not a good sign for the coin:

care to explain how?
Isn't it generally frowned upon to have a single pool control 51% of a coin, let alone 96% of the total hashrate? Or is that only with non-cryptonote coins?
No, can't perform attacks on cryptonote. No way of making double ring transactions.. Only ALT & BTC coins are in the downfall to that. Not cryptonote.
