Hi
Sobi, considering that your rates aren't bad, I'll even talk about small things. The format from what I see is not a problem, pretty clean with bolds and colours, also divided in paragraphs is a good thing as well. Reading the whole rate I just see a point that you missed, you changed the playstyle of the team, at the beginning the team was more like a balanced, but you changed it to a bulkoff, which is not that bad tho, but you made the team pretty Tornadus weak, both sets are really threatening to this team, relying only on the poinson from Sludge Bomb Mega-Venusaur. That's why I'd kept Zapdos. A pretty better rate was more like Oml's one, changing Ferro to Heatran, gaining a Mega Sab + Mega Venu switch, and still not weak to Tornadus, which with ur Bisharp or Weavile, is a huge problem imo, considering that you do not have Pursuit on Weavile and Tornadus is not staying in. After the rate you can avoid tldr's because you have changes in bold, and it's not that long rate to read imo. In hides put just the changes you made, not the whole team after the changes; I think there is not much to say about this one.
The second rate is one that I dont really like, why? You talked way too much about Bisharp imo, he has Low Kick Weavile to revenge kill it, also Rotom-W can "easily" take Knock Off, considering that you didn't talk about the Life Orb set, as well as that you talked about Rotom-W as set up fodder, but it's not right, considering that your chance to KO with the Adamant after Rocks and +2 boost is really low. Changing Landorus-T to Tank Chomp makes the team weaker to Fairies, and removing another Excadrill check + Ground immunity (which isn't a huge miss in this case), but Intimidate might help in this case. He has many answers to Bisharp tho, so I'd focused on other things. This guy made a threat list, which is a thing that team raters should use and try to cover as much as we can tho. Changing one of Tang's move to Rock Slide might helped a lot the team against Charizard Y and Talonflame, which players usually think they can easily switch in that mon. Fixing some Sets like Landorus' one making it able to 2hko all variant of Mega Scizor, making Lando a Rocks SD variant, etc etc.
The last rate, actually I think you put yourself in a "weird" situation, because you rated a pretty confused team imo, you made many changes, 3 mons and 1 set as well as changing that team to a harder and not clear playstyle. Talon needs Rocks removed, Latios is getting Destroyed by Bisharp, which if it gets the boost it's almost gg. Electric with the new version are a huge problem, which with the old version wasn't ( I am not saying that you should have kept Thundurus-T). Imo you chose a hard team to rate.
In conclusion then, I'd say you have to keep following the way you rated the first team, pretty nice and clean one, with a little of mistakes that can easily improve, the second was meh imo, you focused so much on Lum Sharp forgetting many other threats, the third is confused, maybe because of the team which isn't a nice one. My suggestions are these, just do not focus too much on some threats when you rate (Lum sharp in the first and second team) and also consider op's threat list. Thanks for asking advice, we are here to let you all improve, hoping to see you around. Feel free to ask any rater about tips, here, in pm, etc
