Question: what do you think theyll do with summoner
Almost everyones answer : What they want them to do with summoner

Theyll rework it again in order to fit another demi , assuming they still go with the 3 rule. Hopefully they understand that current demi system is stupid and its just stupid ,cause with current logic adding demis just makes rotation timer +1min. The egi gameplay will propably get some tweaks , not rework just tweaks cause it seems the ruin 4 resource management is made to stay. Energy drain will either get removed or reversed , hopefully if they remove it theyll replace it with something.
Worst case scenario the job will be oversimplified but it will never be remade from scratch. Like it or not the job is involved with alot of plot and giving good justification and explanation to its design , it cant be reworked and removed without leaving a massive plothole and alienating alot of peeps.
