Whats up with pali?

Server ticks/snapshots necessitate using Sheltron a fair bit sooner then on-screen visuals would suggest.

There are some weird mechanics that simply cannot be blocked, though; usually things that do fixed/percentage-based damage.

Don't Critical Hits also bypass Block? It's not a problem in Shadowbringers since enemy attacks no longer crit in content from 5.0+, but a bunch of mobs critting in Pharos will still hurt like hell when they ignore Sheltron.
