I agree completely with your points on roaming - at least for me, it isn't fun anymore and I'm mostly idling in PVE nowadays (compared to 95% WvW before), talking to my friends. Perhaps two more points for your list: Roaming classes usually sacrifice damage / sustainability for mobility to help out in many small fights that happen on the map. With the warclaw present, speccing for mobility is nearly useless nowadays - but not all roaming classes can change their builds (for example, mesmers are useless in zergs since the SoI change).The stalemate situation gets worse that people are just calling for reinforcements to break the tie. So basically, people will only engage when they outnumber the enemy - but builds that can deal well in an outnumbered situation feel even more cheesy.
