Talk:Combat boosters revamp (CSM)
From Backstage Lore Wiki
Another thing that becomes an issue and detriment to combat booster usage, is that the skills are EXTREMELY expensive. I've been playing EVE for 5 years, but I'm not a very isk-focused player, and the costs for a full set of booster skillbooks is INSANE. Several hundred million isk for just one of them.
If I could actually get the skills to use boosters effectively, I'd probably buy and use them as they are now. But I'm just not convinced it's worth the isk.
