Personal suggestion For Pvz3e
1.Only Tier 1 plants can be upgraded; all others cannot. All merged plants become stronger as Tier 1 plants are strengthened.The core gameplay of Plants vs. Zombies 3 should be merging rather than upgrading. Isn't it absurd that merged plants are weaker than the original plants?
2.（After first suggestions）Significantly increasing the materials required to upgrade Tier 1 plants while decreasing the materials required to synthesize Tier 2 and 3 plants is misleading. We're here to play Plants vs. Zombies 3: Evolved, not Plants vs. Zombies 3: Upgraded. Making players only see plants in the encyclopedia but not use them, and having to spend a month unlocking them, will ruin the fun of the game!
3.The main story levels are too boring. Although the design is better than before, the effect of merging plants is not so obvious, and the skills are dispensable. More level mechanics and designs could be improved.
