Combo activators not sharing same cooldown as combo

• [ ] Caster 5's R
• [ ] Avenger's R (It does not get put on cooldown put I suppose it is going to be refreshed anyway?)
• [ ] FA's W
• [ ] Gawain's R
• [x] Gilg's R
• [x] Berserker's W

See #59

Every combo should put its activator on cooldown

[sngweicong]

Zerk5's W put on 27s cooldown while normal cooldown is 10 to 6s Lishuwen's E 29 vs 20 Rider5's E 27 vs 20 Archer5's E 27 vs 24 Nero 21 vs 13

The rest are fine. Is this by deliberate design or is it because it was hardcoded many many patches back reflecting the old cooldowns?
