About Mage/Rogue
Phantoms stay where they are if there is nothing to attack. If tank pulls all mobs together, there will be no problem but otherwise they just stay far behind us and do nothing. Can you change phantoms to follow player if they dont have a target to attack ?
We have plans to change the Phantoms in order to summon more of them at a time. We will try to add such behavior to them within that change, but I'm not sure yet what is possible and won't produce performance issues, so I can't promise anything in this regard. The idea is to have up to 8 of these phantoms around you, which will probably be fine. But this will require quite some follow-up patches, as it's a major change of the class. So please don't expect everything will be done within a single patch.
However, I'm also not quite sure when there will be time for the next class update, but I will try to get it done as soon as possible.
Hello there,
after a longer period of time i am looking back here into the game and hoped for something in the patchnotes and didn't find anything about a specific topic.
About the last m/w changes that were made:

1. Was it really necessary to nerf that class that hard? (...)

The nerf was necessary and was only a first step into a new direction I wanted to go with the class. There will come more changes soon, that will add more depth to the class (and cast speed) and address the "Wisdom and Bravery" scaling. The buff gear has been a major problem for years. Everytime we were releasing new content and gear was upgraded, the class needed plenty of balancing adjustments and nobody could predict if the class was about to become entirely broken or not. Our plans will try to fix this at some point. But just like other magical class changes, we can't estimate the time for their release yet.

2. Why in the world did it got changed that rage mana now provides the cast speed and meditative current the magical attack? Feels horrible to play compared to before.
The idea was to put the cast speed behind a condition of sustaining rage, which is only difficult if you don't have a proper rage recovery, but adds some consistency to the class if you do so. Before, you had an internal cooldown/downtime of ~10 seconds after getting the Meditative Current buff and when we removed that, it still felt clunky, as travel delay wasn't triggering the boost in time sometimes, that required wait timers, melee combat or manual interrupts.
Now you can get the cast time bonus instantly and keep it up by 100% of time, if you have minimal resource support or use other ways to recover rage, like white hitting. There is no more slow flame casting snapshot the moment your cast speed falls off while the proc is still on its way to be applied. Now the magical attack is procced on hit, which results into the same outcome but way more consistent than before.
The class actually lost like ~15% damage, which is totally fine for a nerf in one single step. For now I will wait for the implementation of the additional changes and see how the class works afterwards. Probably the upcoming changes will even buff the class a bit but will hopefully make it more consistent in the future.

3. Is the note from the GD only considering the change about the artifacts in this or something else coming up?
Tithing and artefact +12 was predicted to have a decent impact to the class and as it looks like, you can easily get your 2 artefacts of buff gear up to ~lv20-25 which already grants a decent boost. But as I mentioned above, it's always been hard to estimate the real impact of upcoming content properly, especially if the gear upgrade wasn't coded the moment you release a class change. And personally I prefer to prevent potential outliers before they even release, rather than just letting things escalate and adjust later (at least for a class that has proven my point several times in the past already).
I hope that the reasons for the changes are now a little clearer. If you have further questions, let me know or contact me directly whichever suits you best.
Best regards
Wesker
