GMST Class Testing

I have been away some time, so if this may have occurred some time ago, do reverse equips 100% give the bonus indicated in the "All timeless and reverse items list" at level max or am I seeing some CO artifact? Last I remember it was 10% or some low percent like that. In addition, for actual testing, for those that brought max level reverse items into Tespia with you, was the effect added retroactively or should I wait until BB to max level my reverse gear?

Also, back to actual I/L Tespia related matters:
1. Is Meditate a smart buff i.e. can it stack with pots or more unlikely Bless?
2. What damage increase (%?) does ID's ice weakness apply and more directly, does said weakness affect the damage of Elquines? Useful for further DPM calculations I am doing...
3. How was the Ifrit to Equines transfer accomplished, just a basic conversion?
4. Does Buff Mastery affect Infinity, if so, does the percent multiplier pass +100%, I realize few people have level 30 Infinity.
5. It has already been answered but I cannot remember in which thread or page but I remember DoT and Summons are unaffected by both Amp and E.Weaponry, right?

2. I think that ID allow Elquines to hit the damage for elemental weakness.
4. No, I read Dusk's info where Buff? Mastery (>.>) changes 30 Infinity to lasting 60 seconds
instead of 40 seconds and you get a +10% Magic increase every 6 seconds for the duration
as opposed to every 4 seconds. So you still get +100% damage during the last 6 seconds.
5. Not sure about AMP but Elemental Weapons don't affect them from a player in Tespia.
