lol blood is so much better than AoT for sedna
That's for another thread, but my views on a subject, in a nutshell: Cloak > AoT > BotF. Why?
BotF Sedna is great early game, when she can push off/hold flags. That, and a security mechanism protecting from good Regs. However, mid game+ BotF Sed is pathetic. Not just weak. Pathetic. All you have is your half-assed tank hp pool, and no failure tolerance to speak of. That is, unless you seriously plan to invest in J-Treads -- which will mean you failed in your support role and bought an egotistic item instead of giants. Don't even get me started on Silence 2 -> TP, please. It only works in completely non-laggy games, so it's impractical.
AoT, aside from being superbly convenient for a support, gives you one more item slot, which can and should be used for WoS. At 1750, it's a cheap longtime investment that gives you much more failure tolerance than that nooby BotF does.
Cloak is (1) a crappy helm, that solves Sed's early-game mana problems; (2) a superb security mechanism, which does not require any investment into speed -- of course, it does not give you a 100% kill-proof warranty (you can still be chased by persistent Erbs and Occs; usually you won't, though), but then nothing does.
Practically: with Cloak I die once per good match, at worst. With AoT/WoS -- a bit more, as it's more lag-dependent (all clickable items are). With BotF -- the mid-late game turns into 'gank the turtle-like Sedna!' and I always require babysitting, which means I've ultimately failed as a support, since I am the one that must help people out, not the other way round. Again, BotF Sedna is a liability and a feeding source mid-late game.
All that said, I always go BotF when I play with people I do not trust or when a good Reg is at loose
Hate it, though.
IN1 is probably the best support, who plays at the moment
I'd say it's a tie between me and NastyBlade. Hmm... I'm not talking T1+ universal guys, as they rarely play anything but killers (killer QoT counts
).
For integrity's sake, 5nana plays a good Sed, but very non-supportive (no Heal until level 9 or so!). Silvius is good as far as personal skill is concerned, too, but I have a big problem with his skill progression and gearing (not getting HW2 ASAP; getting Plenor before any other helm).
