As for the Jedi, I have no problem with most of them dying. From what we, as viewers of everything since Ep 1, can gather, the Sith do 2 things. Hide in plain sight and train their asses off to fight.
Darth Maul was whoopin' ass on Qui-Gon 1v1, and he went toe to toe with Qui-Gon and Obi-Wan for a long time, and was finally able to separate them.
Palp took on 4 members of the council and skewered 3 in seconds. Then stood ground with Yoda and ultimately came out victorious.
The scrubs in this show were probably run of the mill knights and were clearly no match for Qimir. Sol was a step above all of them, and you can tell his training of Jecki played a role in her ability, and she still got skewered.
Yord showed some smarts by using the helmet against the guy (shout out yellow saber!), but maybe didn't put in the time training how to fight without his own saber.
