Exactly.
Scaling,scaling,scaling problems
Also ETH Metropolis update will bring dapps online store. If some of dapps will become everyday usable I doubt ETH network could functional well.
As we saw recent network crash from simultaneous ICO start. Imagin simultaneous dapps using, also ICOs on network and transactions with switching to PoS! Craziness.
ETH need clear Scalability problem solution first.For Bitcoin it was long 2 year politics war which hopefully will end on August.
They say there is no politic in ETH probably scaling issue will be resolved faster.
Also ETH switching to PoS can bring new glitches to network. Devs made bugs in network before which resulted at DAO hack. Precedent exist.
Look this article below from Tuur Demeester with health criticism of switching ETH to PoS

Alphabay existed for years using only Bitcoin.
After they add ETH, Monero and Zcash they was busted. Obviously it is not coincident.
And noone knows for sure which coin had backdoors. All 3 is suspicious from now.
A lot of bad news especialy Alphabay closure and death of admin. It means no real usage for ETH again.
