Re: pure light mf
117 FCR bp is not worth it if it's gonna cost you 2 SoJs. The dmg increase on L/CL by +2 skills is gonna be much more than 8.3% (e.g. on my sorc, it's 14.9% for L and 10.5% for CL; she's 1 synergy point short and uses 1 skiller), and your other skills will simply be stronger without any drawback.
The % increase of +skills does become less significant the more you have, but in full Tal's even if you had 9 skillers (or any setup with a total of +22 skills including BC), the +2 from SoJs would still give 11.1% for L and 8.63% for CL (assuming maxed synergies, +2 LM Tal Orb).
TL/DR: Don't go for 117% FCR in full Tal's unless you don't have a 35% Spirit.
EDIT:
@above post: No it doesn't kill fast, since it's very poor in the -ELR department. If you are not using Griff's, CM or a faceted JMod (this last one is not recommended), then it's a setup that's inferior to full Tal's. Please read our posts thoroughly.
