Spell rotations / macro generator

[Zub]

added the spell cast times and an indicator of the spell currently in use (the colored line under the timeline icons.
Also added a number of shaman spells and talents, and a few of the paladin glyphs (those affecting cooldowns, durations and cast times: consecration, holy wrath, holy shock and beacon)
Will do the talenst and then the shaman glyphs and talents after.

I haven't got access to the game at the moment, so can someone clarify the following please?

1/ if i have 300ms latency, do i just add 0.3s at the beginning of each cast? or beginning and end? or 0.15 before and 0.15 after ?

2/ i believe cooldowns start when the spell is cast (i.e *after* the cast time)
so if I have a 2 second cast time and 6 second coodown on that spell, I will be able to start casting that spell at:
t = 0
t +8
t +16

3/ If Ii have a 2 second cast time on a spell that has a buff or debuff that lasts for a duration of 10seconds,
that means that if I start casting at t=0 the spell buff will start t=2 and end at t=12

4/The exception being channeled spells where the duration and cooldown start at the beginnng of the casting time. correct?

5/now, the trick is, for Instant cast spells, both duration and cooldown start at t=0, but still there is a *implicit* casst time of 1sec, being the global cooldown. Does that make sense?

sorry must seem obvious but it's late and i'm confused, and locked outside the game
