Beyond gcd healing being deeps loss it is also rather umm.. miserable feeling. It worked perfectly within Swtor which had East Coast servers and stacking alacrity offering 1 second ish gcd. Rouletting into 50 content as White Mage is experience most feist inducing because of this. If someone requires healing now because they stood in the stoopid and Bene is gone you must slow cast cure 2. Hope you are not lagging or the server does not believe you are still moving causing your cast to interrupt. Yes this happens and it is infuriating. Standing completely still > go to cast heal > interrupted > cast again > interrupted > cast finally goes off on myself. ...
All of this made worse by the insistence that we must be facing targets if we wish to cast on them. Nothing like my character twirling around to look the person I am healing dead in the eyes as I clip into mechanics and go dead on the floor.
Unavoidable damage can interrupt casts (please kill this dumb mechanic). Timing a big phat cure 3 for that multi hit stack? Tough! Interrupted! Hope you have Surecast up and did not use it for the knock back.
If you are lagging and the server decides to not register the heal you are required to begin casting again. GCD heals must be planned in advance due to cast time and wiffing one usually results in death or near death. When ogcd heals fail to apply I can just mash into clipping if it means my target lives.
Mentioned before but shall mention again as disserves its own bullet. FF14 has much longer gcd then most other mmos. If we were forced to rely only on gcd healing our total healing output would drop substantially without reduced gcd or buffed gcd heal potency.
Whiiiiich brings a Mia to final point. GCD heals are not nearly strong enough for me to consider wishing to use them. Why touch 700 potency Benific 2/Cure 2 when ED is 900 potency and Tetra is 700 potency. Have not mentioned lilies because those are deeps neutral now and instant casts.
Would probably finally quit the role if they forced us to rely on gcd healing more frequently without serious overhaul to the gcd healing portion of our kits. Make them stronger and more reliable. Also allow them to interact with the deeps portion of our kit in some meaningful way, then we can talk. Swtor did this to great effect! One heal combos into another altering the effect of that gcd heal in similar way to how skill combos on other classes work. Just going from mashing Glare into mashing Cure 2 is only trading one problem for another.
