For me, right-click is pretty much the only way to actually win the game unless you have the OP Frosthaven Bedlam. The viable builds lack diversity, all of them are pretty much:

1. Attack Speed Item or Spell (ex. Butterfly, Fervor)
2. Lifesteal Item or Spell (ex. Satanic, Feast)
3. Bash Item or Spell (ex. Time Lock, Bash of the Deep, Greater Bash)
4. Evasion Item or Spell (ex. Butterfly, Blur, Windrun)
5. Permabash/Perma-disable (ex. Headshot, Pango's passive that applies disarm)

So here are my suggestions to make more builds that aren't right-click or Frosthaven Bedlam.

Magic Damage build:
1. Just like a consumable Aghs, a consumable permanent item that gives spells a chance to trigger two to three times (with a cooldown)
2. A consumable item that allows you to dodge ONE attack, and ONLY ONE ATTACK, NO MATTER WHAT (so you won't get killed in one hit by the right clickers)
3. Have more upgrades to Dagon, but cheaper (ex. 850 gold for the succeeding recipes)
4. Octarine Core + Bloodstone which combines their stats and increases spell lifesteal, mana regen and cooldown reduction.
5. Buff Force of Star but also increase its price to remain balanced

Tank build:
1. Blademail upgrade where it triggers every 3 damage instances or so depending on balance (so it works against both magic and physical damage)
2. Heart of Tarrasque upgrade where you can activate it to work even when damaged by a hero (with a cooldown)
3. Crimson Guard + Assault Cuirass where their stats are combined plus a little more for all the stats, with their passive (Damage Block and Armor + Attack speed aura), and A NEW PASSIVE: Has a chance to block and completely nullify the damage and the effects of a right-click/basic attack. (with a cooldown)
4. Linken's Sphere + Lotus Orb, which just results in Anti-mage's old passive where if you are targeted by a unit target spell, it gets reflected completely. You take no damage from the spell and are not affected by its effects, and the spell is returned to the caster. (with a cooldown)

And yes I commented this somewhere before. I just thought that it'll catch more attention if I post it as a standalone discussion. What do you guys think? If this sounds good hopefully the creators take it into consideration.
