the second one builds great meter. the most optimal meter setup would beAfter a ground pound MB trait I always : dash forward, 3, 2, df1, 3, 2, df1, 3, 2, ground pound for around 47% full combo if I'm not mistaken.
After a df1 MB trait I df1 x4 and then double charge. (47%).
I can do those constantly online I've got good amount of damage, meter, and not so hard executions.
starter xx trait xx lightning kick (5) lightning charge (3). 51%
strict timing but it should build you a complete full meter.
