About losing people, they'll lose people for any change they make, regardless of how good it is or not, there will always be people that find things so little reason to quit the game over. IMO these skills being in the cross-role list is underwhelming, but it's by far not the end of the world.

It's a situational skill, but potentially essential, as not having it can cause instant deaths/wipes. However the same can be said about provoke, which has been a cross-class skill for a long time, and continues in the cross-role system.. nobody complains about that being a cross-role skill. There will be stupid people not slotting it when they absolutely need it and then make weak defenses about why they're not slotting it, and refuse to slot it even after the wipe. You can kick those people from the group.

The thing about the role skill system is simple, they want skills in there that all jobs in that role can find useful. They also don't want to develop too many new skills, so obviously existing skills will end up in there. Essential skills, or those that were already cross-class are the first ones that would cross your mind of things that would be useful.

Further, moving an existing skill to cross-role, and giving nothing in return, does reduce the amount of buttons for the job that sacrificed that skill, as the net result is less additional actions. Note, I'm not using the phrasing "button bloat" there, bloat exists where a skill doesn't have a noticeable impact on gameplay, or when a similar interaction can be achieved with less buttons without damaging gameplay.
