I don't see lack of communication really. Think back to last September. Absolutely awful!
As far as events rn, agreed that we'd like to see some more organization if we get such a huge hero dump. I'd suggest that we go with first newest released, contest for those two, next 2 released, contest for each. While I get Gree wanting to play catch up, I disagree with how it was done. S10 will still be behind other servers now working on 150+ simply because most aren't spending like mad to catch up. I may spend a little, but if there's another raise and hero dump this month? No, sorry.
As to my previous sentence and op's concerns, please put up a small information on plans? Ty team Japan and apologies for non cohesive rambling. Need my morning cuppa.
