1 slot/year is almost like not giving them at all.
I would like some trading ability, not only covers, but also tokens & slots. Kinda like exchange 10 tokens for 1 slot.
HP is indeed hard to get when you’re just starting out. It can be pretty rough, but the prologue should give you enough HP for a few slots. I would focus on leveling 2* characters and sell off your 1* for the time being (Modern Storm is the only exception, as she’s very good for a 1*). You’ll still need 1* heroes for certain tournaments, but you can get to them at some other point.
I managed to get about 30 slots with 3000hp, and I haven’t spent a dime. It gets easier as you continue playing because you rarely get new characters where I am.
I have every cover except psylocke, and then I have alternate builds of several characters. Some haven’t been levelled yet but others have. I have a group of 2 and 3 star characters, most have abilities maxed, around level 30-40. C.Storm, Thor, Ares, MN.Magneto, Spider-Man, and a couple others. Many are alternate builds in the works.
Modern Hawkeye. I’d like to have one with 5 blue and 5 red. Respec is interesting but it’s nice to have options
Classic Storm. I have 5/4/4, but I wanted 5/5/3. Wind storm is too awesome, and that extra turn of stun is really worth it.
Modern Storm, 5/3/5 and 5/5/3. I wanted to see if her Hailstorm was a nice counter to ragnarok’s thunderclap. Nope. I just have 2 squishy storms which I can work with instead of 1. I use them.
Thor, Mine is at 5/4/4 and I made an alt at 5/5/3 before they adjusted him.
Ares, 3/5/5 and 2/3/2. I wanted to have an alt with 5 green
Spider Man 5/5/3 and 3/5/5.
M. Black Widow. Low level verson to use in easy fights. Her stun works just as well at level 15 as it does at 40. Same goes for recon.
C. Hawkeye, similar to black widow. Use to get fast AP in forest. Have to make sure he’s not activating thorned rose.
Most people when arguing about why roster slots shouldn’t be given as rewards is because they fluctuate in price. Putting a cap on them would fix that problem and should make it quite possible. 2 birds with 1 stone sort of.
