I remember when JMK release it was underwhelming too, many said the same things people are saying about LV. Give it a couple days, to get the ideal line up, mods, more people with Ultimate, strategy, and then complain. Also we will have to wait for Maul, just like JMK got much stronger with CAT, LV was also designed to use Maul to get his full power.
And yes that could be considered a bad design, but that's what CG has been doing lately. The thing is that if they buff LV now and then Maul releases, it might make him too overpowered, so I wouldn't like to see changes yet.
