I'm retired and have suffered two strokes, my mental accuity and reaction time is down by a tremendous amount, and even I don't complain about this. While I agree that some of the mechanics aren't intuitive, but once you know how they work, they're easy. I'll give you an example. One boss in Tower of Babil puts these little red bubbles on you. Your first reaction will probably be to isolate yourself from your team mates. Actually, you're supposed to stop attacking and stand still to avoid damage. This game is leaps and bounds ahead of others with it telegraphs, but it isn't perfect. Don't let the nice orange cones and circles lull you into complacency. If you're unsure about a boss's mechanics, look them up. Or, if like me, and you have a physical limitation, tell your party before-hand so the tank and healer can adjust their pulls and rescues for you.
