Lack of rogue hirelings is the main reason why I stopped playing this game back in 2013 when I started playing it.
When I was playing with my RL friend one of us had to be a rogue so that we could disarm traps and open locks.
That means one of us had to give up on playing a pure class, or multiclassing a non-rogue class that would better fit its character and take few levels of rogue. And that person would be very unhappy because of that.
And why? Because back then, on older threads like this one, rogue types complained that rogues are weak/useless in combat and no one would want them in a party if they don't need them just to disarm traps.
Well we already have rogue hirelings for platinum on epic levels! So why are heroic rogues still TP/AS only? And why are new players still forced to take rogue/artificer levels to be able to run through quests normally?
Back then people complained that these hirelings are bad for disarming traps. Now we have new quests that require very high skills to detect and disarm traps so these rogues wouldn't even suffice for these new quests. So player rogues would still be prefered over hirelings.
I don't think there is any strong reason nowdays to keep rogue hirelings TP/AS only. They should be available for platinum, just like epic level rogue hirelings are.
You could maybe make several artificer hirelings that would have much better trap detection and disarming skills needed for new quests and then make these new hirelings TP/AS only. But old rogue hirelings that are good enough only for old quests should be made available for platinum.
If there is a business reason behind keeping rogues TP/AS only, maybe you could sell this availability in the DDO store. Like 1000 DDO points for the permanent account ability to buy rogue hirelings.
People shoud be able to play without forcing them to ruin their build because they can't buy rogues as hirelings normally!
