Did Grievous improve after TCW Season6?

He had to retreat from Kit Fisto in TCW, but he holds his own against Mace during the Battle of Coruscant.

No. Filoni simply opted not to treat Grievous as generously as some of the other mediums have... Which is a shame, imo.

I didn't mind Grievous being reduced to a moderately talented Jedi killer in the face of Force users.

What really bothered me was how underwhelming he was as a commander.

Yeah, as a military strategist he came off as an inept feeb more times than not. Really is too bad that he has that type of stigma these days. Most other types of media --be them novels, comics or cartoons-- have portrayed him as a brilliant leader whom was skillful enough to give most Jedi a run for their money(under the right circumstances, of course.)

How the mighty have fallen. 🙁

Hmmm. Hard to tell. He kicked ass on Hypori, but then all the Jedi their may have been weaker than Kit Fisto.

It's not like he clashed with Windu for too long.

All the Jedi there were more exhausted than Fisto, and didn't know what to expect either. They'd all been involved in a long running battle.
