rogue t15 4pc reduction now 15% instead of 40%
5.4 PTR Update

- Eviscerate data was wrong. Turns out Blizzard never fixed the data
from a stealth buff during beta. Everything matches dbc values now.
- 2 Ambushes won't fill a CP bar. Doesn't support anticipation-less
well, but it's good for the brief moment.
- Rupture only costs 25, not 35 energy.
- Removed old Sub code. No longer serves a purpose.
- FW multipliers improved. Could be better, but this is monumentally
better than it was a month ago.
- Shifted damage and energy with t16 4pc appropriately now.
5.4 PTR Update

- Vanish Glyph doesn't reset the full MoS buff, just the stealth
portion.
- Force openers to Ambush for Sub.
- Better job accounting for CP's from openers.
- Removed double dip in ambush costs from Shadowmeld.
5.4 PTR Update

- Fixed Several Sub typos, bugs and increased the accuracy of several
modifiers to handle uneven distributions of actions.
- Better support of casting SB at various times. Stack CDs uses one of
3 predetermined strings instead of a boolean: 'shd', 'fw', 'other'.
