It took me several months to unlock all of the units/characters. After all, I was once a complete and utter noob at this game.
The 74-Z Speeder on Endor is still very good, as is the T-47 Airspeeder on Hoth, while the V-4X-D on Crait is decent vs. troops and great vs. the AT-ST, TIE, & the ionized AT-M6. The BARC, & STAP (only real use is to damage the AT-TE) are quite bad, and the only real use of the LIUV is to shield team members who are either setting or defusing the explosives.
IF they had simply raised the battle points cost of these units to 1,000 it would have greatly helped to mitigate their impact. A 1,000 BP cost LIUV would have prevented an officer from the quick start battle command, re-spawning, & owning in the 1st phase. Still, both sides had this ability with the LIUV, and the Resistance also had the added bonus of a 1st phase A-Wing and X-Wing. Both of which can/will decimate an LIUV.
Sure, you can still run over units with the LIUV, but it seldom registers for damage or elimination, and the primary weapons are practically useless. So yep, one of the funnest units in the game was ruined with the speeder nerf, in addition to the LIUV being blocked from going up the back ramp on Phase II to access the Main Gate area.
Yeah, the Celebration Edition was a joke of a last ditch effort to garner more funds and players. However, the fact that it wasn't usable offline made a lot of buyers unhappy.
