Is rogue a single or multi/dip into class?

[RogueJK]

Played an AT high elf with BB to 11th. Sentinel is a damage boost, but with reliable talent I took skilled. Did feel in combat was fading as T3 rolled around but out of combat/role play just got a lot better...

I played a similar AT with Bladesinger dip into Tier 3. I never felt like I was lagging in combat. Reliably landing large amounts of damage using Booming Blade + Upcast Shadow Blade + Sneak Attack is a good feeling. And being able to slap big enemies with a disadvantaged Suggestion, Hold Person, Hideous Laughter, or Levitate (my 8th level any-school pick) is handy.

The sneaky magical hijinks out of combat were a highlight though, having all those additional spell options like Mage Hand, Minor Illusion, Fog Cloud, Silent Image, Invisibility, Suggestion, Phantasmal Force, etc. to assist you, not to mention your Familiar.
