The expansion clickies are not modified if I understood well.I don’t like this change and they are deprecating the value of the very expensive teleport clickie for ultimate expansions.
Only the spells teleport, greater teleport are modified to behave like the clickies.
I personally, believe that the best solution is something in the middle.
Teleport, greater teleport, recall used by scrolls, clickies should behave the same with the expanded teleport clickies and have some casting time. The same for the golden key and d12.
All should get standardized with the same casting time, cool down, interrupt mechanism.
It is clear for DDO that all these have no combat intention and are for QoL. Adding a normal casting time, cool down mechanism reduces abuse and might possibly reduce lag.
But memorized spells or SLAs should allow quicken to reduce the casting time and prevent interrupt. While not the direct intention of these spells, creative use of the spell by players should not be prohibited. If indeed the intention of the devs is to stop the use of these spells in dungeons, then just do not allow the casting of these spells in dungeons. (Keep them only for wilderness and public areas).
As I mentioned earlier, personally I would restrict teleport within the same plane of existence and wouldn't allowed it to change planes.
For combat use, DD exists and I'm sure that if they wanted to make money from DD they could simply put a DD clickie at next ultimate version of an expansion.
