An excellent thread (and a good idea to show it in a consolidated format to indicate a portion of the scope of -current- discussion of the APAC community's perception of the problem)
Personally I am in favour of instance consolidation based on content (grouping people by language and game area supported game play types (eg areas where PvP is not supported, can obviously consolidate both PvP and non PvP designated characters) server connectivity (server location of instances generated to be based on server utilisation, based on rule set application (such as PvP enabled sections being located on PvP servers) and/or client latency (which would be more important were a cross regional approach used, but less so given BW's current system architecture design)) rather than a more general region based server consolidation approach. Though given the size of the APAC user base, a regional approach is probably sufficient tbh.
Regardless, some form of player consolidation is necessary in order to preserve a MMO dynamic, otherwise, one must concede that the APAC SWTOR will soon degenerate, no longer capable of being called a ' Massively ' Multi-player game and the dependant game features - such as war zones - will become increasingly untenable unless BW takes steps to consolidate a disparate APAC player base.
