The way other games approach the 'rogue' class is with high mobility and stealth while placing emphasis on an opening attack (ambushing your target). This game enables what the majority of others condemn.. virtually endless stealth if you build for it and the counterplay does exist but it's low risk for a high reward. I'd recommend changing so that thieves have the option to toggle a permanent stealth outside of combat and give them an elite skill that places them back in stealth while removing conditions. To compensate for the new lack of spammable stealth, let's give Thieves more access to evasion and maybe a temporary disarm/parry mechanic. This fits the class thematically and can be tailored for any existing trait lines. I doubt many would have objections for this new style of gameplay.
