How Latency Affects Maximum Healing Potential

Latency plays a huge role in determining how effectively you can heal and what your maximum healing potential is. Consider this, if you are spamming heals with a 1.5 sec cast time, then you could potentially make 40 heals per minute. However, add in 100 ms of latency, and suddenly your cast time becomes 1.6 sec. In this case, you can only cast 37 times a minute.

Now this may not seem like a huge difference but look at it this way. With 300 ms (therefore a 1.8 average cast time), you could cast 33 times in 1 minute, which means that you could have suffered a 17.5% loss in your maximum healing potential. The subtleties of latency are intricate and so perhaps I am overstating the facts a bit, but any way you run the numbers you are still gimped in your healing ability depending on your latency.

Take another example. If 300 ms translates into 0.3 sec of extra cast time, then there would be no way I could keep LB stacks on 4 targets at once.
1.5 x 4 = 6.0 sec
1.6 x 4 = 6.4 sec
1.7 x 4 = 6.8 sec
1.8 x 4 = 7.2 sec

Each cycle now exceeds 7 sec (the time of LB) and therefore keeping 4 stacks on 4 targets would now prove impossible. That being said, it’s probably possible to make a 4-target cycle work with latency over 300 ms just because of the intricacies of latency (which I don’t understand thoroughly enough to give comment or direction). But for our purposes, we’re going to assume that 300 ms of latency translates into 0.3 extra seconds of cast time.

How This Information Affects Trinket Selection
The main thing I want to use this information for, is to discuss the way certain trinkets proc if they have a standard chance per cast to proc. For example, if a trinket has a proc rate of 2% per cast, then we assume that it will proc once every 50 casts. With absolutely no latency, this translates into 1 proc every 75 seconds (50 x 1.5 = 75). However, with 300 ms of latency, this changes the proc rate significantly to (potentially) 1 proc every 90 seconds (50 x 1.8 = 90). This can significantly change the value of that particular trinket, so when choosing which trinkets are right for you, please be conscious of your average latency, and how it will affect that trinket’s performance
