the issue is you cannot command summons anymore you get a one time attack or an auto rotation (bahamut phoenix) and thats it. cause they couldn't fix ghosting or AI (which is all people wanted really not an entire ducking rework). it's why i suggested PSO2s pet combat where you essentially have a snappy movement start casting the pet jumps onto the enemy and sticks on the enemy until you change targets or recall them/replace them with another summon. you could even take this a step furhter by having the summons themselves have cast bars for certain abilities allowing you the summoner to do an extra instant cast while they're building up their cast bar
