Rogue gang up and fighter lunge mc feat

[RagingBarb]

Just wanted to make sure this combo is actually working the way I understand. If you go rogue, mc fighter through archetype dedication and get the lunge feat for class feats 2 and 4 and then get gang up on lvl 6, this would allow you to attack with finesse weapon from behind the group tank and still get your sneak attack in at reach? This would definitely help to mitigate the squeeshiness of the rogue while still contributing to damage considerably.

Yep, that should work, though your target will probably get lesser cover:

Chapter 9: Playing the Game / Encounter Mode / Movement in Encounters / Cover wrote:

Source Core Rulebook pg. 477 1.1

When you’re behind an obstacle that could block weapons, guard you against explosions, and make you harder to detect, you’re behind cover. Standard cover gives you a +2 circumstance bonus to AC, to Reflex saves against area effects, and to Stealth checks to Hide, Sneak, or otherwise avoid detection. You can increase this to greater cover using the Take Cover basic action, increasing the circumstance bonus to +4. If cover is especially light, typically when it’s provided by a creature, you have lesser cover, which grants a +1 circumstance bonus to AC. A creature with standard cover or greater cover can attempt to use Stealth to Hide, but lesser cover isn’t sufficient.

Cover is relative, so you might simultaneously have cover against one creature and not another. Cover applies only if your path to the target is partially blocked. If a creature is entirely behind a wall or the like, you don’t have line of effect and typically can’t target it at all.

Usually, the GM can quickly decide whether your target has cover. If you’re uncertain or need to be more precise, draw a line from the center of your space to the center of the target’s space. If that line passes through any terrain or object that would block the effect, the target has standard cover (or greater cover if the obstruction is extreme or the target has Taken Cover). If the line passes through a creature instead, the target has lesser cover. When measuring cover against an area effect, draw the line from the effect’s point of origin to the center of the creature’s space.

The biggest hang-ups are probably:

Having the necessary 14 strength for the Fighter Dedication (a thief won't normally have the strength, a ruffian could use an actual reach weapon, and most of the other rackets have another highly-valued stat)
Remember that Lunge is a distinct action, so it can't be combined with other 'make a strike' actions like Opportune Backstab (Losing this feat could cost you a lot of damage).
