System/clan
Horseman
Reduce damage: 15/30/40% >>> 20/30/35%.

These changes are aimed at reducing the “hegemony” of the Hecarim Hecarim Magician in DTCL season 5. However, it seems that Riot is not really making this team disappear. Typically, the squad revolves around Hecarim will only play with 3 knights. Besides, the key general of this flag is that Hecarim is not “touched”. Perhaps Riot will have to do more in the update 11.12.
General
There will be up to 2 devil generals who are reduced in the update of 11.11b.
Kennen
Kenen will now reduce the pressure that can cause the main route mainstream.
Blood: 650 >>> 600.
Mana: 40/100 >>> 50/125.
SETT
Reduce the scope of damage of skill.
Mana: 0/40 >>> 0/50.
Except for armor: 20/25/40 >>> 20/25/30.

Sett is also one of the most powerful generals in this update because of its “unreasonable”. With three items equipped with town, Sett can “punch and die” most of the most buffalo tankers in DTCL season 5.
Varus
Physical damage: 65 >0> 60.
Promote: 0.80 >>> 0.75.
Lulu

Since the 11.11B update, Lulu will probably not be considered a faulty chess pieces in the DTCL season 5.
Mana: 50/100 >>> 40/100.
Time to toad: 2.5/3/3.5 seconds >>> 1.5/2.5 seconds.
