How to improve: 621-Druddigon

1.Stats: Should Druddigon get a stat boost, Evolution, Mega Evolution or nothing?

In both of its appearances Druddigon appeared in late-game areas, Dragonspiral Tower and B2W2 and XY Victory Roads. This means though Druddigon is a common Dragon, it is a late-game Dragon. But it only has a measly 485 BST. This means that Druddigon is actually one of the weakest Dragon-types, and has the lowest BST for a fully evolved Dragon-type.

This simply cannot do. So, what can we do? Well, an evolution can work, but Druddigon is already slow, so +50 more boost would not fix Speed, but it might make its defenses good or its Special Attack usable. A Porygon-Z style reorganization can also work, but it would mean that Druddigon would have to lose some of its trademark bulk for Speed.

A conventional stat boost suffers the same fate as an evolution. +10 is good but not enough. +50 is necessary for Druddigon to have some relevance, which is simply too high.

A Mega Evolution is rather infeasible without some stat buff first. It would require a type change and/or strong Ability to work.

2.Should Druddigon get more abilities?

Druddigon's abilities are fine, but lacking. Rough Skin is relatively meaningless for Druddigon since most people will not hit it through physical contact moves. Sheer Force is irrelevant because it doesn't buff a STAB move. Mold Breaker is only useful against Levitate and Flash Fire.

With this in mind, some other alternatives would include 

1. Contrary
2. Intimidate
3. Iron Fist
4. Poison Heal
5. Poison Touch
6. Solar Power
7. Sniper
8. Super Luck
