Riot, for Season 7 can we please get some additional Vision support?
Okay so Season 6 is closing out. In commemoration of this, I'd like to talk about warding. So back at the beginning of Season 6, you guys made some massive changes to the vision system, which included a blanket nerf to all existing vision items, a nerf that ended up making the Farsight Alteration easily the most effective option for getting team vision throughout early S6.
Along with those blanket nerfs, you guys also removed the option for purchasing stealth wards, a change that made it incredibly difficult for non-support players to keep their lane safe, and on a much broader scale, made it much much more difficult for laners to assist in team vision. After season upon season of making changes to alleviate warding responsibility from support players, you ended up hoisting vision priority almost entirely on them, as after nerfing Farsight into submission, you guys provided very little support to the only remaining viable team vision tool accessible to non-supports outside of a single pink.
So What kinds of things would I like to see in S7? Well if you guys are still adamant about not having stealth wards available in shop, at least bring back the greater stealth totem, because the warding totem is just really underwhelming, and honestly just kind of bad at its job.
For instance, let's take a look at the maximum possible warding options available to laners through this item.
At max lv
wards last for 2m, and stores a charge every 90s.
If used as it comes off of cooldown, a player can have a maximum of 2 wards out for a maximum of 30s, before their first dies.
If used at 2 charges, a player can have 3/3 warding for 30s as well, before 2 of their wards die.
Even if staggered, a player cannot have their ward count at 3/3 for more than 30s.
And this, is late game lv18 ward coverage. The values only get worse as you pull back. At lv6, Wards last 78s (1.3m) and recharges in 153s (2.55m) Meaning 3/3 warding is impossible, and 2/3 is only possible if you wait for both charges. In fact, 3/3 wards is only possible in the current iteration at LV 15 for the grand total of 3s. (109s last/ 106s recharge)
So Riot, please. For Season 7, lend us a bone. Alleviate some of the support warding burden by giving non-supports options to contribute to the team's vision in meaningful ways. Whether you bring back Stealth wards, return Greater Stealth Totem to us, or something else. Give us the option to make a noticeable and consistent difference. Help top laners not be such gank-fodder, Help make the map a brighter place, if even slightly.
