Doing 2+2 once vs doing 2+2 5 hundred times makes the whole difference.
If a heal has complexe calculation (means that the servers has to gather alot of information around, update the results to every person in raid, and often has to do that a couple of times PER spell, for every spell, every second. At some point, some of these information have to be queued for a few MS, but when it gets out of hands, players will notice a input lag, simply because the server has already alot on its hands, and the spell players are casting ask alot more than it used to.
