My first two Raid experiences. Not impressed. New EXP grind
So I did my first Raid this morning and I am not impressed at all.
First, the raid boss was an electrabuzz. when battling its moveset was thundershock/thunderpunch. After defeating it in about 5 seconds, I caught it. Its IVs were around 80% and its moves were Low kick/Thunder :(.
Received 3000 Exp for winning, could be a new way to grind EXP with lucky egg as the raid passes are free, you can use 2 free raid passes in 1 day (save the raid pass from the day before, pop lucky egg, use raid pass on first raid battle. Spin gym stop to get the raid pass for the current day and use in next raid battle within the 30 minutes lucky egg window)
I proceeded to the next raid battle by HBO. Spun the gym stop and received my next raid pass. The new boss was Weezing. Again, beat it, caught it and the moves it used in the battle was not the moves it had when caught. It used shadowball in battle but ended up with sludge bomb when caught. Again, 3000 EXP for winning.
Rewards from firs battle

Rewards from second battle

I think, the reward is great. I would keep the rare candy for legendaries, and the golden berry for a more rewarding raid-boss. Even when used for normal rare pkm, 3 rare candies is like 15 km walking.
I think, i would prefer a raid level 3, let alone 4, over two thirds of an incubator. I hope, there will be raids level 4 too, and i hope, they reward Technical Machines.
