Guild Wars 2

The Mesmer’s portal ability is a lot of fun to use, but also incredibly inconvenient to keep track of. Apart from the fact that once both portals are connected they only last half as long as their tooltip says they should, and often are bugged and completely unuseable, there is no way to know how long you have to cast an exit portal other than keeping a stopwatch near your play area and resetting it every time you cast an entrance.

This is a horrible mechanic. It is of course possible to mouse over and see which ability is in line to be cast – the entrance or exit – but once the entrance ability comes back up you’ve already missed your opportunity to connect to wherever you were trying to connect to. The ability absolutely needs some sort of visible timing mechanism. A simple buff on the player with the white timing border (like boons and conditions) would do the job wonderfully, and should not be difficult to implement.
