Granted, despite everything said about, it is not ENTIRELY bad. However, IS needs to show some actual foresight on the ramifications of their choices.

The fearful part I have is that this is going to happen again next year if IS decides to do it again. If they do another massive migration of Book II units out of the new hero summoning banners, we'd lose a TON of meta relevant characters, especially when considering that the Meta has pretty much settled on an established set.

Just picking out some of the strongest units we received in Book II, we'd lose Karla, Owain, Ophelia, Micaiah, Zelgius, Fallen Hardin, Fallen Grima, Book II brave units, Ishtar, Swordhardt, Myrrh, Lewyn, Maribelle, and Flying Olivia. And those are the ones I could think of off the top of my head. Those are all powerful units that will be ubiquitously removed next year if they pull this again.
