Whiles I am preening with delight we get both - even though Alliance players butt sore about it even if they can still go to Suramar in 7.3.5, if you had to choose one though which one would it be?
If blizzard decided, hey, we can't really give the horde both elven cities, they can have only one and the choice was either to have the High and void elves take over Silvermoon or the Night elves to take over Suramar, which would you prefer and why? State which faction you are.. and ify ou are both factions, just pick which option appeals to you most.
- I'd rather Silvermoon, lose Suramar - I 'm horde
- Gain Silvermoon at all cost, they can have Suramar - I'm alliance.
- Suramar all the way, I can live without Silvermoon - I'm horde
- Suramar without a doubt, strong ties, they can keep Silvermoon - I'm alliance
**EDIT ADD
Un-updated Silvermoon, I presume that won't be forever.. if we get a race expansion, every race will have a capital -- well every major race, as I suspect racial capitals will be your race's order hall, since every race actually has a city already built, it's just a matter of decorating those who don't have homes like Gnomeragan for example will have that stuff restored and Silvermoon will get its update. Trolls will have Zuldazar, and with a destroyed Darnasuss, night elves will either have Suramar or it would be the high elves/void elves that have Silvermoon and it be the alliance Elven city. So we might have both cities for now but there is a real chance it won't last. Besides I don't see the alliance seeing the status quo as fair and will moan about it forever, still, I'll enjoy the tears till it changes. And if it does change, which one will you rather keep and why! Factor in the possibility that Silvermoon will be updated into your decision.
