Maybe his lower chance to weaken is balanced by the fact that he can reduce healing and block cooldown skills?
Hey Victory - I think this is probably the best argument against it, being that it would be unbalanced to give Twinclaw access to 3 different debuffs. However, one important thing I looked into was comparing all rares with access to [Weaken]. Here is the list:
Twinclaw, Orcs - a2 - 50% chance of 15% [weaken]
Grappler, Skinwalkers - a1 - 15% chance of 15% [weaken]
Halbedier, Banner Lords - a1 - 25% chance of 25% [weaken]
Interceptor, High Eves - slightly different, due to possibility of other debuffs.
Bone Knight, Undead Hordes - a1 - 15% chance of 15% [weaken]
Stitched Beast, Undead Hordes - a2 - 25% chance of 25% [weaken]
Wanderer, Dark Elves - a1 - 30% chance of 15% [weaken]
Harvester, Dark Elves - a1 - 35% chance of 15% [weaken]
Bulwark, Dwarves - a1 - 15% chance of 15% [weaken]
**addition** Hellfang, Demonspawn - a2 - 50% chance of 25% [weaken]
It is important to note that Twinclaw also gets a 50% chance. However, the cooldown counts against this percentage, as even with a high percentage Twinclaw does not have access to it every turn being that it occupies his A2 spot. Also Stitched Beast attacks TWICE, each for 25% chance, which is similar to Twinclaw's single hit with 50% chance, yet Stitched Beast benefits from the 25% [Weaken] debuff.
If you notice in the list above, any champion with a 15% [Weaken] debuff has it in their Attack 1, meaning more frequent access. It makes sense to lower a % debuff in this space. However, all champions with [Weaken] in their Attack 2 have a 25% [Weaken] debuff.
The other champions have access to similar debuffs as Twinclaw, so the number of debuffs in his kit should not prevent him from having access to a 25% [Weaken] debuff as is the norm of other champions in his rarity class.
