In my eyes, the current current agility dodge system is flawed and leads to many people having misgivings about high agility low defence builds.
As of right now I'm using a build with around 140 Agility (~75% dodge chance) and 0 defence, resulting in the following ehp calculations:
- Effective HP: 31923
- Effective HP (no agi): 10565
If i were to instead use a build with 140 defence (~68% damage reduction) 0 agility i would get the following ehp calculations:
- Effective HP: 32782
- Effective HP (no agi): 32782
While both of these cases have similar ehp values, it is safe to assume most people would rather use the latter build.
Why?
In this case, due to the randomness associated with agility dodges, a 75% chance to dodge instead feels like a % chance to get hit twice in a row (or more) with only 10k ehp.
In an example where you take 4 hits (same damage), the odds that 2 or more of them don't get dodged in a row is around 13.3% (this would increase for longer hit "chains", which is usually what happens in game during, for example, a lootrun challenge or a raid challenge room). Unfortunately, taking quick successive hits at 10k ehp is usually a death sentence to most archetypes.
Meanwhile, with a defence heavy approach those 4 hits would always result in taking equally damaging hits for a total equivalent damage of 1.28 hits at 10k ehp. This results in a much better survival chance since each hit will be relatively weaker and the burst damage window will be much greater, allowing for more time to react appropriately by either escaping from danger or healing.
