I don't like the new TT as TT.
I'm not sure what meta the old one was 'locked' into (i saw no particular meta that my team abided by) but all it needed was for some walls to be thinner and the champs to be less glitchy (lee sins shield would sometimes be pretty much an invulnerable)
IMO i think you are making the wrong decision by not making it a separate map, it is a BRILLIANT map but it is in no way twisted treeline bar the same number of players.
You yet again have claimed to listened to the community but what i see is most people asking for the old tt to stay too! Remember dark valkyrie diana? On most polls about 75% of summoners did not like her new design but you failed to listen, this will be another case of that im sure.
You claim to want the game mode quicker and with less turdling, but putting a massive wall in base is preventing champs that cant dash to be able to defend the base at all in close games!
-Vilemaw is still a bit too strong considering that it's meant to be a quick game!
-I like the alters but you should still leave the wards!!!! Champions like teemo with shrooms will be deadly with no wards! If a team wants to play it safe then let them! Just boost the price or reduce the duration or something. I'm sure you don't want any particular champs to dominate!
My issues with the old TT: glitches on champions, walls too thick considering that they hadnt been changed since flash was nerfed, CC TEAMS unavoidable i know but honestly they were the main issue, and the changes you are making dont help!
I find that the new map is a 'jump in head first' kind of playstyle, not suited to characters like zyra and such who were still good (who is another example of a champ witha n unfair advantage due to her plants if there are no wards!)
TL;DR
It's a great map but i still agree with most in saying that it needs to be separate. The issues old TT had are not being fixed by you changing the game mode entirely :/ also wards are needed unless teemo is not allowed on the map.
EDIT:
I would also like to point out i rarely see that low of an upvote score on a news item, if that isnt indication enough on the communities opinion!
