In Torchlight II, having high Focus attribute points can greatly benefit any class that deals elemental damage due to its numerous benefits across various aspects of gameplay. Here are some key takeaways from the provided text:

1. Increased Elemental Damage: Focus directly scales all forms of elemental damage without introducing diminishing returns (DR). This means investing in Focus will consistently increase your overall damage output, making it an attractive choice for players who rely heavily on elemental damage.

2. Mana Pool Increase: Beyond just increasing damage, Focus also contributes to a larger mana pool. Having more mana allows you to cast spells and use abilities more frequently without needing to worry about running out of resources during intense battles or long boss fights.

3. Execute Chance Bonus: When dual-wielding (equipping two weapons at once), Focus not only increases auto-attack damage but also adds an additional chance for executes on hit. Executes deal significant bonus damage, making this stat particularly beneficial in high-damage situations.

4. Overpowered Nature in Vanilla Game: The text explicitly states that the Focus attribute is 'massively OP' (overpowered) even without any modifications or patches applied to the game ('vanilla'). This means players who invest heavily into Focus will have a significant advantage over others, especially early on in their playthroughs.

5. Quick Leveling and Easy Progression: The first 30 levels of Torchlight II are described as progressing very quickly. Coupled with the ease at which any two-player team can handle most content, even on higher difficulties without much effort (thanks to the game's relative casual nature compared to other Action RPGs in its genre), players should be able to get a feel for their build and playstyle relatively fast.

In conclusion, if you're looking into building an elemental damage-focused character in Torchlight II or are new to ARPGs but want a more accessible experience while still being able to deal significant damage, investing heavily into Focus attribute points early on is highly recommended.
