I never paid much attention to this, as everytime it was mentioned it was always a message about 'SOF users' using clickys, so therefore I never paid attention as I use Titanium for all my clients.
There are some clickys I had been using (ie Targins on my wizard) that I never gave a second thought to, as I have always used clickys from inventory that did not contain my class (Dark Elf mask from Guk being the perfect example back on live), and as there were some clickys that gave the 'your class/race/diety etc may not use this' I took it as these that people were using SOF client to exploit and use.
I remember back on live a nice perk was being able to use a clicky on an item from your inventory that didnt have your class on it, so always took it that this had followed over to here.
Is it a rule here that if it doesnt contain our class, we shouldnt use it at all?
