Shortly after OG took their second Major victory, Valve has released the 6.88 patch, featuring limited nerfs and multiple buffs for the under utilized heroes.
Smaller in scale compared to the previous patches, the 6.88 patch has brought about some nerfs to popular heroes and multiple buffs to the lesser picked ones. Item changes in this patch center around cooldown reductions and a redistribution of stats, most notably the extra five agility points granted by a Butterfly (35 agility given, up from 30).
Unsurprisingly, popular heroes leading up to the Manila Major and at the Major itself received either nerfs or no changes. Death Prophet, with a 60% win rate at the Manila Major, has had her Spirit Siphon - a popular first skill to max - base drain damage reduced by nine points, from 25 to 16. Bounty Hunter, holding a 59% win rate and the most banned record at the Manila Major, also faced a similar fate, having the self-gold given by Track reduced from 170/260/350 to 150/250/350.
On the other end of the spectrum, under-utilized heroes such as Phantom Assassin and Outworld Devourer have received buffs. Phantom Strike is now able to target spell immune heroes and Essence Aura's mana bonus increased from 75/150/225/300 to 125/200/275/350.
With the patch notes in mind, the current meta is not expected to shift too much, therefore, it is unlikely that the patch heavily favors any team.
