It seems like Sim is set to have new changes in SF5 season 2 according to Eventhubs below, he seems to have the most changes of all if this for real. I knew couldn’t have left him in his current garbage state.
Dhalsim
• Crouching Medium Punch has better horizontal hitbox can hit chars further away.
• Stand Heavy Punch is now a crush counter, beware fireball throwers.
• Hitstun on limbs is now plus on hit, so it means you will have to respect his far limbs a lot more.
• Previously, Dhalsim’s far reaching limbs were minus or 0 on hit, so you didn’t have to respect him after being hit, now it’s different.
• Yoga Anvil (Back + Heavy Punch) reduced in startup from 12 frames to 10. No more brainless jumping in.
• Back + Medium Punch went from 8 frame startup to 6 frames now.
• Hearing V-Skill has much faster startup, and float jab has more hit and blockstun so you can’t just hit him out of it.
• Standing Light Kick went from 5 frames to 4 frame startup. Dhalsim can punish easier now with it.
• Standing Heavy Punch feels way faster!
• Slide Trigger buffed, flame doesnt go away anymore.
• Some of his far reaching limbs can be cancelled into super. Far range st.HP crush counter xx Super is a combo.
• Air Heavy Punch is slower.
• Down-Back + Medium kick is a real low which is ideal for midrange foosties.
• People overall seem pretty hyped about how good Dhalsim can be in this version right now.
