Or the fact that the ability to gain healing amp is a universally shared trait and not a loophole for the Warforged's healing resistance.
I don't know how I can make this any clearer... Sneak attack damage is the same damage type as critical damage, this is on the programmer's level and fundamental to basic D&D rules. That's why both are stopped by Fort, that's why Sneak attacks are not multiplied on crits, and your persistent retaliation is naught but arguing semantics.
The Highest DPS -NOT- having aggro while being situationally useless..... Lowered fort permits crits and sneak attacks, but not 100% of the time... the Rogue still has to contend with the fighter's naturally high damage and damage boosting effects, so unless you are commenting on a dual Heavy Pick rogue versus held mobs with Fort, the balance is maintained between Fighters and Rogues until you venture into a dungeon without Fort (sweeping Fighter favor) or face the undead (Fighter slamdunks again).
This keen differential in mechanics keeps Fighters favored in epics and a far cry everywhere else.
