XP-system as nothing to do with themepark games, it's just.. a XP-system.
It's all about casual and hardcore gamers.
What can be said to Davion-like players,
- Perpetuum is only 1 year old game, joining now a game who can last 5+ years will still give you opportunity to be the old vet you want to be.
- You don't need that much EP to be a specialist.
- Very large EP pool mean all-around player not God-mode.
- An extension from 0 to 8 cost less EP than from 8 to 10.
- An extension from 0 to 9 cost is very close to 9 to 10 cost.
- Difference between a full level-10 specialist player and a full level-8 specialist player isn't that much. I mean it's not like a lvl40 against a lvl50.
- Most extensions give like +1% to +5% per level, so if we round this up to +2.5%, the level-10 will have 5% more than you on each extension, yes it's better but not unbeatable.
- Perpetuum isn't a 1v1 game, it's team-based. Mean you will team with some vets.
- Smart young players can crush stupid vets. a smart lvl40 still get owned by a stupid lvl50.
- Extensions are limited to lvl 10, a super old vet will still be lvl10 in your speciality extensions, you will reach his level some day.
- NIC is very important and you need to play to gain NIC. A young rich player in heavy mech will crush the poor vet in arkhe.
All i try to explain to you is, with few months of EP, you will be a very strong player in an area you did choose, while the old vet will just spend this extra EP in some other areas because he's already maxed in yours.
TL;NR - Very large EP pool mean you can be multi-task player, not god-like player.
There might be some rare cases where this can be wrong, like Pit's Troiar ?
