Im fairly new to WoW I have 40 ish hours and have around 100 battles played. Im currently on Calorado, I have all the xp needed to reach North Carolina on my grind for Montana. The issue is I still need 7 million more credits. I recently opened a tier 8 destroyer Cossack, which happens to sell for like 7.2 million. I know that premium ships espcially tier 8's that can get uptiered to tier 10 games can earn lots of credits. But im wondering is it worth to just sell the Destroyer and buy the North Carolina as im not a very good destroyer player or should I try and get better at the Destroyer and use it to earn the money I need to get North Carolina? Please Help.
