Changing to POS + MN was a great decision , monday cant come fast enough

show me at least one good approach in any PoS interpretations - besides the fact that PoS is the compete opposite of brilliant PoW and just centralizing asset around holders with bigger bags - there was no good looking approach anyway. so walk me thro how is moving to PoS is a great decision?)
There won't be 51% attacks via PoW and a similar attack via PoS is a little more complicated especially since there are masternodes.
One big attack vector removed.
do you know that pos has more attack vectors than pow so far?)) so you removed one, then added another three and how its better
