Can´t agree with this, I´ve been playing Bayo1 for the last weeks and I´ve found that the Alfheims do teach you a lot of stuff. The ones about using only Angel Arms or Torture Attacks were great to develop tactics for Infinite Climax difficulty. They are also much more challenging in general than Bayo2´s. Maybe 1 is more focused in advanced tactics whereas 2 tries to teach/strengthen the basics.
In general, I found Bayo 1 much more harder than 2. Apart from the usual suspects in the comparison (QTEs, Route 666 and After Burner Stage) I think that Bayo 2 shines when looking at the weapons. In 1 you have a lot of weapons, but not that much variety:
1-Scarborough Fair=Guns=Bazillions=Shotgun=Killgore
2-Shuraba=Pillow Talk (only in hands)
3-Whip (only in hands)
4-Dhurga
I still haven´t unlocked the nunchaku and am not going to count Rodin.
You have a total of 9 weapons, but only 4 really different movesets.
In Bayonetta 2 you have:
1-Love Is Blue=Guns
2-Scarborough Fair
3-Rakshasha
4-Shuraba (only in hands)
5-Bow (only in hands)
6-Kulshedra
7-Takemikazuchi
8-Chernobog
9-Fire/Ice thing
10-Chain Chomp
11-Salamandra
You only have 3 more weapons, but they give you 11 different movesets. More different weapons can be equipped to both hands and feet, creating even more options. And the most important thing:
almost all weapons feel different. Love is Blue is used for a quick fighting style with long combos, Chernobog is slower but is better for crowd control, Takemikazuchi can easily destroy single targets and forces you to dodge offset to get the most out of it, Salamandra rewards you for extending every hit and looking for the just release but takes away the importance of ending combos, the whip allows you to easily reposition your enemies, Chain Chomp is a beast in close combat that also has great reach if you extend your hits and can send the enemies flying (and it even attacks on its own)...In Bayonetta 1 the only difference between many weapons is only in the powerVSspeed category.
Anyway, I´m having a blast replaying Bayo 1
