I agree with you and I am not debating that is probably what they are supposed to be. I just question whether SE is going in that direction or not. I think we can both agree that being a tactician means using the right ability at the right and in the right situation. With that in mind let me explain to you why I think SE is either going in the wrong direction or is all over the place. It really has to deal with the 3 abilities I talked about before, the fairy gage, quickened atherflow, and the new mp management scheme.
For a second lets first throw out the low chance of this happening, but to have the greatest opportunity to take fully advantage of the quickened atherflow trait you have to use your atherflows at least once every 10s. If you proc all 3 you reduce the cast time by 30s, anymore then this will run the risk of some of the cool down not counting. Is it likely to happen, probably not, and in this case you just blew through all of your atherflows in 30s - 50s. They then linked fey gage and fey union to the use of atherflows. This further incentives the use of atherflow to quickly build fey gauge for fey union. Finally they built the mana regeneration and mana costs of the class around the use of atherflow every time it comes off cool down, giving more incentive to use atherflow so you are not waisting them. What this means is that SE is pushing the player to use their atherflow within the 30 - 60s cool down of the ability but not necessary to use the abilities locked behind atherflow in a tactical manner. Can you still do it, absolutely, but you are being punished for saving the atherflow to use that wanted ability at the right time. With the current set of abilities there are times when there just isn’t a need to use all 3 atherflows within the cool down time. It was more advantageous to save them for when you did need them. I did this all the time before all of these different class aspects were attached to the use of atherflow. In fact I felt most comfortable when I had a full set of atherflow and the cool down was up. It gave me the most tactical advantage during fights. Scholar today puts you at a disadvantage for trying to play this way.
To be honest, there are many things they could have done with these 60 - 70 abilities that would further reinforce the tactician style of play. One idea would have been to make the atherflow trait have a 20% chance to return 1 atherflow and 3% mana to the caster. This would reward you for using your atherflow when you needed to (tactician style playing) instead forcing you to use them in a set time frame. Another thing would have been to completely de-link atherflow with sch mana regen and just centered it on something else. This also would helped to reinforce tactician style play. Finally they could have just completely used a different system to build fairy gauge, further reinforcing the use of atherflow skills when the time was right. They could have done any of these things without fundamentally changing the play style of the class, but they didn't. Instead they put in abilities that are counterintuitive to the tactician style play they had been building in HW and partially in SB.
