honestly, if you are looking to hold ships in buy-back, and you are not looking for LTI tokens...don't bother.
This year, we have the Fury. Unless you have a friend with a big ship to carry you around to be cannon-fodder in, this is a really bad ship. It can't go anywhere on it's own, and while it's fast, maneuverable, and packs a punch, it's also made of glass. I don't expect it to be able to take a beating long term.
Lynx....yep, it's an Ursa with a drink package
Storm - this one is interesting. It's single seater tank that has control over a S3 weapon. It's one of the few ground vehicles you don't need two or more players to pack a punch with. That said, i am also not expecting it to be very well armored, and I am also expecting it to blow up running over the odd tree root
Now, if you were going to CCU those to ships you plan on playing, THEN get some of them as LTI tokens as well as the appropriate CCU. The Storm offers the best deal at 10 bucks warbond below credit value.
As for what ships...what game aspects are you interested in? a ship with a T3 bed? a ship with lots of cargo room? Fast Fighter, Heavy combat ships, ground forces? Once you decide what you want, but the upgrade and KEEP IT. Don't melt it.
Honestly, buy the ships you want and don't keep chasing the meta. Nothing will remain as it is long term. It all needs to be balanced once it goes through beta...
