"The only Sednas I've ever had issues with are fed Sednas. The regen doesnt hurt too much. At lvl 5 I do 945 dmg every 15 seconds. She can't regen that fast. It's a mana war, not a BURST HER DOWN HURRY! fight. You need to heal quite a lot, considering that TB AA does over 200 until you get armor.
Once you are level 5, Deep Freeze takes care of pounce which gives Sedna VERY little damage."
At level 5 38 hps on top of monks which are healing 15% of my max hp which will typically be around 3k every 8 seconds~ 450.
In 16 seconds my regen is 1508 damage. I don't think your 15 seconds includes AA which is roughly 130 (Level 5 DPS is 129, but you have form dancing, but then I also have armor and the Weapon-Damage+ buff isn't always active either) which adds 2080 damage to me. Plus, it really is wrong to assume the weapon damage buff is always active. It takes 2 seconds to change forms and so on.
So, all in all you're doing roughly 2080 + 945 damage - 1508 = 1517 damage over 16 seconds, making a large number of assumptions. Then what happens is I will heal then start backing up to my tower (making sure there is no creep wave coming up that you can farm or you recently blew your BotS) you will walk forward to contest the flag, I turn around the second it turns yellow. I will push you off the flag (without pouncing because pouncing is lame). Then I will-recap the flag, and I will pocket that free ~125 expierence. I'll do this to you twice by the time we are level 5, so typically I'm already going to have a slight level advantage over you in that I'm hiting levels abougt 30 seconds before you are.
If I am healing while you are kiting me I'm timing it with the mana flag (heal immediately after you cap it, or heal immediatly before it drops if it will oom yourself)
If you stop trying to cap the flag, then I'll just farm by my tower instead.
25 seconds is an eternity. I'm not looking for them to pile up. I'm looking for exactly that. Spending 25 seconds on grunts."
I typically still pull creeps/monks though. If you pull them you can directly AA attack them. It takes 6 seconds to kill 2 priests with just AA. Plus, again. I'm ignorign you as you hit me with AA. I really am. I really... just don't care that you're hitting me with it. I've been laned against plenty of good Ice TBs. Until Level 5 you can out-kite me pretty easily. You'll probably push me out of a lane Level 1 just from kiting. But when you turn a flag to Yellow I turn right around, healing as neccassary. Again, I'll try to be timing this to deny you creeps to feed off of mana with BotS but that may not always happen.
Though you do get two pots so it is possible that you are more difficult to push off of a lane than other TB's.
Also? What do you do first 15 seconds? Do you fight for the XP flag or not? I don't, I barrell straignt to the HP flag and I also go around the side so I get +4 xp. If you are sharing the XP flag with one other person then you're only getting 50 xp. This means you're going to be aleady disadvantaged from and expierence perspective. You'll almost get it back if the XP flag remains uncontested for 2 full creep waves but most of the time people are exchanging the Mana and XP flags.
I don't remember how long the +weapon damage lasts from form dancing. It helps to push but it tends to disappear around the time I turn around to contest a flag, I have found.
Also, I'm only pouncing if you are about to fireball me, I'm not doing it otherwise. I'm saving my mana for heal.
