All would be for it, either once per Character or long Cooldown.

The only possibility is the server merge. One server for US and one for EU. For EU, since the game is anyway built on instances, you can, for example, where you now select the servers also on EU select the EU Server and the language, English, German and French. Then you get into the respective language channels where only the language is spoken and you can manually change the instances as now and also the language instances you can change in the game. PVP and PVE of course all together. If there are equal names, the subscriber has priority and if both have subscriber, counts who created the character earlier and the playtime on the character. The auction house is of course complete for the whole server.

Please bring out a Second Combat Style Reset Token for the Cartel Market. Applicable once per character or 1 time per year.
