[1.2.279] Skill nerfs this time

Marksman
- Snipe - This is a STRING change, not a skill change! They changed the max level of snipe to show 5 seconds instead of 4. This is strange because the skill data still says 4 seconds.

That's because even with a 1 second cooldown in the data, we'd only be able to shoot it every 5 seconds anyway.

B> pierce adjustment so that it's actually as useful in reality as it looks on paper.... seriously, charge up and low HP don't go together, and the damage distribution should be changed. The 6th mob is massive overkill so on paper its ZOMG AWESOMESAUCE, but in reality I need to shoot 3 to take down a mob of guardians at oblivion, the last dies on the first hit so all that potential is wasted 2/3rds of the time unless I manage to make a mob > 6. but DB only pushes 6 so it's not that easy.
