Been reminding people the update is still NEW! Therefore take the game as it is, because the update will iron itself out. Interesting read, they left TTar alone? Not bad, all of this was expected though. Personally was only going for Machamp, TTar and TMs. Be interesting to read for percent change if any on TMs.
This is why ive been saying it was better to catch these in the wild as they are not as hopped up on sugar and trainers have the ability to use ultra balls to increase their catch rate.
Before trying to catch and level 4 raid tyranitar was almost impossible even with golden raspberry+curve ball+excellent throw. Ive had them break out as soon as the ball hit them, not even a single shake.
Now the same is true for the rest of the level 4 bosses. The starters I didn't even bother with because they were near to impossible.
