1. Unclear yet but I agree, definitely at least tier 3.
2. Unclear but my gut feeling is between tiers 2-3. It's still bulky, just not as good as before.
3. Gardevoir never belonged into tier 4, at least for high traffic areas. Hardcores in my area have rated Gardevoir higher than Snorlax since last winter, I would say Togekiss goes to tier 2 and Gardevoir to tier 3 now.
4. No. Shuckle gets an average tankiness value, which makes it a very good gym point denial tool, but it's almost strictly worse to Wobbuffet, which also has next to non-existent decay, very low point gain for the enemy, is significantly tankier AND resists Machamp.
1. Very much agree.
2. Breloom can occasionally top Machamp in TTW, it gains a lot from the buff to its tankiness. Tier 2 seems appropriate to me if Machamp is tier 1. It's the next best option now.
3. Roserade is a bit worse than FP Venusaur as grass, but that high of a poison DPS does have some merit. Same tier as FP Venusaur, regardless of what that tier is.
4. Seems low for a pokemon with such good DPS. I'd rate Weavile stronger than either Exeggutor.
4.5. I can't understand how Exeggutors are above FP Venusaur. Their secondary types are so severely outclassed that they don't matter much for attacking.
5. Agreed.
6. Agreed.
7. Yes, they are. Especially with the numerous upcoming psychic legendaries, Gengar deserves a bump to at least tier 3.
While this kind of an exercise is fun, I think as a whole the tier lists need a complete re-evaluation.
