Light tank: Scorpion, Swift Wind, Skulker. Not a lot of great light tanks. At 25 tons and using a 100 ICE it is cheap and has SRM and LRM variants. The others are scouts and pretty good at it.
Medium tank: Vedette, Goblin, Hetzer. The Vedette isn't fast enough or with enough armor to stand up to much. The Goblin has a LL and a one ton infantry bay, nice. The Hetzer has an AC 20 but crap armor and a 4/6 speed.
Medium support: Hetzer SRM and LRM, think light SRM/LRM. More armor than other support vehicles. I like using multiple variants of one base frame and 30 SRM's or 30 LRM's is decent firepower.
Heavy Tank: Po, Pike, Manticore, Tokugawa, Bulldog, Brutus, Zhukov. The Po is a decent AC 10 carrying tank. The Tokugawa is the same with wheels. The Pike could do with less ammo, seriously, do you really think someone will let you shoot 225 times at them with an AC 2? It is slow so it isn't running away, better pair them with Demolisher's. The others are decent depending on cost and how you like to fight.
Assault Tank: Partisan(AA), Demolisher(AC 20 x2, say guard tank for 3 LRM carriers), Behemoth, Schrek, Ontos(LRM only unless city fighting).
Hover: Pegasus, Saracen, Saladin, Scimitar, J. Edgar, all fast and with weapons to harass the enemy.
VTOL: Warrior, Cavalry, not a lot of good designs here, almost an after thought throw them a bone selection. A 30 ton design with either a 100 ICE or 160 ICE can get you lots of SRM's or LRM 5's and a troop bay along with MG's. No cannon designs that are mission specific or should I say a good one for every mission. The Ferret for scouting, Warrior for attack, etc. but you could come up with 3 to 4 variations on the same frame to cover all the missions but only if you design them.
I personally dislike fusion tanks that don't take advantage of the 10 free heat sinks. So Hunter, Rommel, Patton......Where is the LL or PPC? I would much rather see a PPC on the last two and a LL on the Hunter. The Hetzer LRM beats the Hunter on number of LRM's and by a lot in cost. Think PPC, LRM 15 in place of the AC 20 and PPC, SRM's in place of the AC 10.
