Can we make DFT work like Liandrys?

Rather than just keep buffing it's scaling to match with Thunderlords can we change Deathfire Touch to deal more damage to crowd controlled targets?

This way it's scaling doesn't need to be enormous to be relevant, but it's still good on the champions who want that kind of ability (AD casters and mages who all have utility). The damage would only be there when you land a CC, thus rewarding you for hitting it.

I'm not saying as strong as Deathfire Touch was before the last nerf, but maybe a better balance between where it is now and the power that Thunderlords carries behind it.

Right now, generally speaking, burn damage < burst damage. Thunderlords gives so much burst that most people are going to take it because of how relevant it remains at all parts of the game. Deathfire Touch is also magic damage and doesn't benefit from taking armor pen if you are an AD caster (yet has a higher AD than AP scaling), where as Thunderlords has the double pen mastery right above it.

It seems like without some kind of extra play to Deathfire it's always going to be a battle between it and Thunderlords, and Thunderlords almost always wins that fight (especially because it does more damage early and games are shorter).
