In my opinion they are a top team that is very strong and can certainly compete for top arena spots with little issue...
This is of course considering a maxxed out droid team with all the gear and zetas that are equivalent to your opponents...
Since the separatist droid rework I’ve been running them in arena and take #1 easily on a very old shard
I use two variations depending on my opponent... but it’s an easy swap and still a straight up droid team... even using HK lead for one setup which everyone complained was now useless (it’s not)
I think a lot of people just gave up on them with all the negativity surrounding their rework on the forums and failed to realize their potential.
The droids might well be the best all around answer to the current meta and in my experience can most efficiently and easily beat the cliche teams that everyone else has gravitated towards
The Bastilla rework had made zero difference in my ability to crush JKR teams... and DR teams are so stupidly easy to beat it’s almost ridiculous... I think the addition of Malak only made them easier to beat quite honestly...
Being able to just click auto and decimate the other team in under 30 seconds is pretty silly for top 10 arena battles...
The droids are good... really good...
If you are willing to invest in them and realize their potential :)
