That is part of dumbing down I mentioned before. They could just remove shriek and decrease the enmity modifiers on the combos and magically, you have enmity management again.
That is absurd. Do you want to increase healing? Just make the bosses auto attacks do 5x or 10x more damage. Problem solved, now healers actually have to heal and you still have a lot of defensive cooldowns which are now necessary and useful again. Also the trinity also requires tank to actually tank and not just be glorified blue dps like thay are now.
Saying that tanks are more different now is seriously disingenuous. The way tank stances worked was MUCH more different than the way they do now. WAR had a different skillset between the bloody stances...
Gauge/gimmicks were added to all classes. It really only makes sense on WAR and they just added it to the other tanks because they had to add a gauge. And WARs gauge actually has a meaning since you need to do some resource management compared to other classes. Not to mention the classes still have gauges.
Yes tanks had a lot of tools that had similar usage (some were required) and instead of making them more different they just made them even more homogenised.
No it's not. Both are mmos, both use the trinity and both homogenised their classes. It's also a live example of what happens when you homogenise too much. It's a very appropriate example.
Raiding in WoW and FFXIV is pretty similar. WoW also has LFR so pugging is a thing there as well (WoW probably has better raiding because they have more bosses and difficulty scales better). In FFXIV you can finish most content with PUGS because the content is not punishing/difficult. You can clear normal modes with pugs. But that is not true for difficult content. Try pugging an ultimate.
