The four iconic solos in game were not well received by the community so I highly doubt they would take the manpower and time away from something else that needs done in order to do them. Good idea imo, but I do not see it happening.
i received them very well, but never gave my 2 cents. they were awesome for me considering back then i was pretty much controller only. solos these days aren't so friendly for those that only have a controller armory with only controller gear.
I never had a problem with them, but I remember the venom spewed in the forums over them. Most players want to play as their toons though and were quite vocal at the time if I remember correctly.
The issue was we were limited to play ONLY as an iconic for the solos in those two episodes. If there were solo Legends in events I'm sure that would be well received.
