Not really. Those companies (Gamerica/UOL and Axeso5) have the licencing rights to RS in their respective languages. It's not an advertising deal. So basically you wouldn't ordinarily see Jmods on those worlds because they don't speak spanish. So these guys take over doing the Jmods events?
With tetsu and dual drygores you have all the gear you need for Vorago. (well, a cks or fks would help if you don't want to pay for a spirit shield). The hard part there is just building skills and finding teams.
My understanding is that trim comp isn't removed from keepsake boxes unlike normal comp. Because #jagex. (Also, there were people in keepsaked trim comps before anyone had killed Vorago)
