You obviously watched a very different show than me. GI defeated Kanan without any troubles twice before he was finally defeated by him, and only when Kanan had his Rey moment, when he thought Ezra is dead. Ahsoka is far from a Jedi wannabe. By the end of the Clone Wars she was pretty much one of the most powerful Force users out there and could go toe to toe with Maul. The trick they used against the Inquisitors in that episode was pretty smart and it was their only option how to survive. They knew they cannot defeat the Inquisitors in direct combat. Technically they are lowly Dark Side pawns, however they still are a real threat to most Jedi. I'm not sure you realize that most Jedi out there during the PT era are far from the power level of Yoda, Mace, Obi-Wan or Anakin. In the movies and TCW, we always follow some of the most powerful Force users in the galaxy, however the Jedi Order has around 10,000 members and most of them are far from the level of the likes of Obi-Wan and Anakin. For you average Joe Jedi, the Inquisitors are more than enough of a challenge. About the newest issue, like the art, however I'm not the biggest fan of the fact that the Inquisitorius already exists and has so many members this early after ROTS. And they all look the way they will look in 15-16 years. Hope there will be some real explanations about this in the series, otherwise its pretty lazy writing IMO.
