Is it Worth Keeping and Powering Up 2-Star Pokémon in Pokémon GO?

As an avid Pokémon GO player, you‘ve likely accumulated your fair share of Pokémon ranging from 0-stars to the coveted 4-stars. But what about those middle-of-the-road 2-star Pokémon? Should you invest your hard-earned Stardust and Candy on powering them up? Or transfer them for more Candy to evolve 3-star monsters? This is a common dilemma, so let‘s dive into the pros, cons and things to consider when deciding whether to power up 2-star Pokémon.

How Common are 2-Star Pokémon?

With Pokémon GO‘s appraisal system assigning stars based on hidden Individual Values (IVs), the majority of Pokémon caught, hatched or raided will end up in the 2-star range. Based on community research, approximately 65-70% of wild spawns will be either 1, 2 or 3 stars. Among them, 2-stars make up around 30% on average.

For perspective, that means for every 100 Pidgey you catch, around 30 will earn 2-star appraisals. The chance of finding 0 and 4-star perfection is extremely rare outside of trades, raids and eggs. So for many trainers, powering up 2-stars is inevitable to build battle teams.

Why Do IVs and Stars Matter?

IVs influence a Pokémon‘s maximum possible Combat Power (CP) at each power up level. The higher the IVs (and stars), the higher CP potential a Pokémon has. For example, a perfect 15/15/15 IV Dragonite caps out at 3525 CP at Level 40. With 0/0/0 IVs, the max is just 2349 CP. That‘s a massive difference!

Higher IVs also provide a small boost to Attack, Defense and Stamina stats. Combined, this makes 3 and 4-star Pokémon clearly optimal. But 2-star IVs still translate to decent combat performance.

How Do 2-Star Pokémon Perform in Battle?

While 3-4 stars should be priority, powered up 2-star Pokémon can absolutely hold their own. Here are some key factors to consider:

• A Level 30 2-star Tyranitar will have nearly 90% of the TDO (Total Damage Output) of a 4-star Tyranitar at the same level. That 10% difference rarely makes or breaks a raid.

• Pokémon typing and movesets matter far more than IVs. A 2-star Machamp with Counter/Dynamic Punch will outpace a 3-star Blissey against a Normal-type defender.

• CP caps in leagues like Great League (1500) and Ultra League (2500) mean high IVs are less critical. A 1400 CP 2-star Crustle performs essentially the same as a 4-star in this limited meta.

• Defense and gym longevity care less about IVs. A high CP 2-star Snorlax or Blissey holds gyms perfectly fine compared to a less powered up 4-star.

When Are 2-Stars Worth Powering Up?

• When stardust and candy are plentiful: If you have resources to spare, boosting 2-stars of rare or meta-relevant species like Larvitar, Dratini or Beldum can be worthwhile to build raid and gym teams.

• When 3-4 star alternatives aren‘t available: For Pokémon with scarce spawns/candy like Gible or Deino, a decent 2-star may be your only option.

• For PvP leagues with CP caps: Maxing out 2-stars helps stay under 1500cp or 2500cp limits. And you save dust/candy compared to powering up a 4-star.

• To round out your best raid counters: Focus on 3-4 stars first, but level 30+ 2-stars can fill gaps in your teams once resources remain.

• When high CP is prioritized over IVs: Maximizing CP for gym defense can justify powering up high-level 2-stars like Slaking or Snorlax caught in the wild.

Drawbacks of Investing in 2-Stars

• They max out at a lower CP than 3-4 star Pokémon at the same level. You‘ll notice this especially at higher levels.

• Less overall stat power. You‘ll do less damage per second compared to ideal IV alternatives.

• Later, you may acquire and invest in a stronger version, making your 2-star obsolete.

• More candy and dust required to hit damage breakpoints that 3-4 stars can hit more efficiently.

The Verdict? Evaluate 2-Stars on a Case-By-Case Basis

While trainers shouldn‘t make a habit of powering up every 2-star they catch, it can certainly be worth it situationally. Evaluate each one based on rarity, resources required, alternatives you have, and intended purpose. With the right considerations, you can get great mileage out of 2-stars and make the most of what you‘ve caught.

I hope this detailed guide gives you a better understanding of when to invest in those middle-of-the-pack 2-star Pokémon. As you build your roster, be selective and only power up the ones that will have the highest impact and value. Happy hunting, fellow trainers!
