I wouldnt go drow.
Mostly because of capstone.
What I mean is - as SH u could get Free CLW (which hits with metamagics for 70-80, 170+ on crits with 30% heal amp item only, without it 50-60) . U san say its low. Well Heal amp tanks can be succefully healed this way all quests. And its nice to help yourself when ure low on sp.
To ass here u get nice free click (even tho with loooooong cooldown) - u can remove all dead penalties, and its a "heal? that hits for 1k if theres a need.
Or Id choose SF capstone - free saering light. With metamagics its like 200+ on non crit, 400+ on crit. So welcome free dps.
If u want to melee or offensive cast invisibility really gets u nothing, ad for invisi healing u can get click on pots. Easy to get.
Human definitely is better option. Even +1 feat gives u more than these drow points.
And the build u linked is solid one.
Its what I did for mine 1st life fvs (just went elf, cause well.... cause its pretty
But going to TR human). Mine fvs is 20 currently and is good.
I just throwed out Greater Evo Focus, and picked up Shield Mastery,
