Rek, Sai, Thoughts?
Ok, this is a place for meaningful dialog, not random blurts of, OMG too much knockups of new champs or blah blah blah
honest thoughts with actual reasons/evidence for appropriate situations
Quick summary of spell details (that are not 100% apparent from ability text but are from vids of sampling spells)
passive: fury gen, heals....some ammount when burrowed, consuming fury, this is only ability that consumes her fury, generates on AA speculation: passive says " dealing damage when unburrowed" not basic attacks or abilities, could imply synergy with things like hydra, but probably doesnt.
Q: un: next 3 hits bonus dmg and AoE burrow: skillshot that reveals, important for keeping track while burrowed. Unclear as to if this resets your attack timer or not (probably does)
W: un: burrow into ground, gain MS, lose virtually all visuals (from your character, other sources such as wards, and allies still show) and your "footstep" tracker, cannot use basic attacks while burrowed Burrowed: burst out of ground, doing dmg and knockup, cooldown is SHORT but has a per target CD (like udyrs stun)
E: un: bite, more fury, more dmg, true dmg at 100 fury. Good if you have extended trades but since you likely will be closing the gap with the MS from burrow and its knockup getting the true damage might be....limited and mostly effect jungle.
Burrow: dig a tunnel, dashing you forward (relatively slow for a dash) but leave tunnels behind. These tunnels can be destroyed by being stepped on (like zyra plants) but last for 10 minutes if left alone, max of 8 tunnels, Tunnels can be REUSED to replicate the movement of the ability on a relatively short CD (unknown time, but you do have to wait between when you reuse the tunnel again), these can be used to cross walls even on secondary uses.
R: passively gives AS: good for generating that fury, overall DPS increase. Synergy with on hit based factors
active: Global ( or virtually global at least) teleport to existing tunnel from burrowed E. 1.5 sec cast time+ travel time (quick but not instant) ANY hero or tower dmg (not just CC) will interupt the channel, unclear as to whether this interupt puts it on CD or if CD only if spell successfully goes off. Speed boost on successful Teleport. Also causes you to be burrowed when you exit
Personal Thoughts: An unusual champ like Kalista with boat loads of Utility at the cost of raw power. burrowed Q likely to be a low dmg spell all game if it scales with AP for some reason (does magic damage, it might, unclear at the moment) but i could be wrong. Follows a recent pattern of Riot of making champions with "easily defined weaknesses" SIon rework had MASSIVE telegraphing, Kali has relatively low firepower (relative......) Gnar has the forced split playstyle allowing different champs to capitalize on one form or the other.
Rek sai's appears to be Risky Vision. You are NOT invisible while burrowed, and you have VIRTUALLY 0 sight when burrowed, sure you might be able to follow a juke due to the sonar like effect of w....but you WILL NOT be able to see spells!!! if you are running at low health and need that SLIGHT dodge to avoid a hook or skillshot, you likely will never see it coming to know when to dodge if you are burrowed (for that extra MS you want).
That being said the map mobility and control is HUGE, able to scout out enemy junglers from a safe distance with echo location, create quick travel highways with long duration tunnels, and the ability to split push with the freedom of ultimate, combined with teleport, can always be ready to show up at a key location or capitalize on an opportunity. Also capable of massive jungle objective stealing. The first use/return of the tunnel is ready immediately, a well warded Rek sai can hop over a wall with cast of E, smite steal Drag/barron/red buff, use the tunnel to go right back over.
Also synergy with on hit based effects, which are quite strong (i know the devour er is getting nerfed) due to the permanent AS steroid in her passive, also works on waveclearing with hydra for that split pushing monster.
While clearly advertised as a jungler due to the pathing from tunnels i see no reason for this champ to do well as a top laner. Fury Consumption on her passive helps sustain the lane, you are a manaless champ so you can go ham with spells even on minions, your tower is likely to almost never be touched due to short CDs on Q and W. You can run TP to gank another lane, then return to your lane with your R (and leave behind tunnels for future ganks as well. If well coordinated with jungler can easily be ready to invade enemy jungle with them if they help your lane enough (or you dominate it). can do some harrassment pretty easy with burrowing in with a tunnel then using the tunnel to back off to avoid trade damage, your AS should let you build pretty tanky (thinking tri BorK/Hydra depending on pref and need then rest tank) Sounds to me like a pretty strong top laner (though probably still best in the jungle)
How do you plan to build/play her? What kind of champs do you think she will excel against and suffer against? How do you plan on playing against her?
