The only tool I can think of the game needs is a DPS meter that is strictly available in savage. The whole reason they don't have DPS meters in general is they don't want what happened in WoW where you get elitist behavior, but savage itself there's no real way around it because it has an enrage and a lot of the jobs still need work to get them to a point that a DPS meter is unnecessary. Like no one running reaper needs a DPS meter, but some jobs like BRD and DRK definitely do.
I do feel that some people want tools to solve problems that can't really be solved by tools. Like if someone is constantly getting walled by add phase on p3s, that's either on them not understanding how it works, or getting into groups where people do not understand how add phase works. That and a lot of groups stuck on adds keep using the worst strategies for adds so they got nothing to blame but themselves...
Bah, now I went off on a tangent on savage when talking about tools. I suppose that is normal since tools are there to make difficult things easier.
On another note, people mentioning WoW and not wanting this game to become like "WoW": This game will never become like WoW for a whole lot of reasons. First, WoW was released in 2004 during an era where a lot of games were released in buggy states, so you'd have college students and all sorts of people making mutators, mods, and sometimes even patches to fix these games. So companies at the time had a much less strict policy on third party code when it came to gaming.
Now we are in an age where the internet has matured, online access via broadband, fiber, and cable is ubiquitous in many places, and gaming as a service has become a major model. Companies aggressively defend their IPs and want to monetize everything, including cosmetics, so it's created a culture where your average modding college student is probably going to get a ban just for fixing some clipping issue.
