I agree with most of what you've posted but I'm going to have to disagree about your reviews on Talia and Consular.
Talia can only heal by sacrificing her own health and with the improved AI now that seems to target healers first more often than not you end up losing her faster. Her basic attack that can heal her hardly does enough to keep herself alive, not to mention her third skill is currently bugged and doesn't do anywhere near as much damage at it should. If she's the only healer you're using in your team then you're in trouble.
EDIT: I should add that these comments are in reference to Arena PvP. Of course you will need Talia early on in order to progress through the Dark Side Campaign as she is your only healing option until you can get Old Daka.
Jedi Consular on the other hand has a crazy nuke and at higher levels/gear has a solid heal that can have its cooldown reduced by 1 permanently and also has a 25% chance to reduce all cooldowns when doing a normal attack.
Also, IG-88 is still decent for damage if your team is full of debuffers since IG-88 has a passive skill that when upgraded allows you to have +30% crit damage and 15% more damage for each enemy under a negative status effect. Granted as a new player on a budget, your options for debuff characters are small so Sidious is still the first option for Arena shards.
